Learning to Shave

My last post covered some natural whetstones I bought. I also mentioned the Japanese sujihiki kitchen knife I sharpened with the natural whetstones. I don’t usually pay much attention to the handles on my kitchen knives – I have both Japanese traditional style (called wa in Japanese) and western style handles (called yo in Japanese).

But the handle on my sujihiki kind of bothered me – it felt coarse in my hand and the transition from the ferrule to the wood handle wasn’t smooth. I never liked the plastic ferrule either. I saw a sale notification from Tokushu Knife for replacement wa handles. Tokushu Knife is located in Tennessee and the handles they had on sale are locally made and looked to nice. I ordered an ebony handle with a padauk ferrule.

Tokushu shipped promptly, but the USPS fumbled. Tracking showed the handle leaving the USPS facility in Chattanooga with no further information for a week. Then it showed it at the USPS facility in Memphis. What did they do, walk it to Memphis? A week to progress from Chattanooga to Memphis is ridiculous. It finally arrived here after 10 days or so.

Getting the old handle off wasn’t an easy task. I tried several methods and in the end I had to use a chisel to split it. I found hot melt glue holding the blade tang to the chestnut wood handle. I had tried heating the knife by submerging the handle in boiling water, but apparently the wood insulated the glue and it wouldn’t melt. I didn’t want to overheat the metal.

It took about 30 minutes of filing with needle files to get the fitment of the new handle right. Then I shaved a hot melt glue stick and put the shavings inside the handle opening. I heated the tip of the tang with a kitchen torch – the type you would use to glaze sugar on creme brulee. I held the blade by the spine near the heel – the heat never went past the tang. The blade slid into the hot glue and I let it set for a few minutes. It was a great fit. Everything is aligned and the depth into the handle is just right. Altogether it took a little over an hour – I was thinking it would be a 20-minute job.

I have another kitchen knife story. The dollar is very strong against the Japanese yen right now. My most recent purchase was a nakiri from Japanese Chef Knives. It was made by Teruyasu Fujiwara from pre-laminated Yasuki Shirogami #1 steel and is part of his Nashiji line of knives. I love cutting with it. But, I couldn’t help stepping up to the next level – a Teruyasu Fujiwara Maboroshi Nakiri. I had to order one and wait for it to be made. Teruyasu-san has three levels of knives he hand makes. The entry level is the Nashiji line made from pre-laminated steel.

The next step up is the Maboroshi line. These have the same shirogami core steel, but the stainless cladding over the core steel is hand forge welded by Teruyasu. This means it is repeatedly heated and hammered and this changes the molecular structure of the steel for the better. The pre-laminated steels use the same materials to make a three-layer blank, but they are made by running the sheets of steel through a high pressure roller. This works well, but it can’t match the quality of hand forging.

Very few bladesmiths have the ability to forge weld the hard shirogami core steel to a soft stainless cladding. I can only think of a few. Most Japanese bladesmiths laminate soft iron over the hard core steel, which is easier to do but it negates the advantage of using a stainless steel to cover the corrosion prone core steel.

By ordering direct, I was given the choice of a custom kanji on the left side of the blade. The right side has the Teruyasu usual signature. I asked Ayano at the customer service if he could create a kanji for Koop. Apparently this was a hard concept to create phonetically, so he offered a couple of suggestions. This is what he suggested:

【光峰】: “光” means luminosity or brilliance, and “峰” means a high mountain or peak. This kanji symbolizes that the person is a person who brings brilliance to those around him or her and pursues the heights to which he or she should aspire.

It might be a little over-the-top, but I went with it. After about nine weeks, I received an e-mail telling me the knife was ready to ship. They sent me pictures.

The knife arrived two days later and it was worth it.

The custom kanji side

I’ve been doing dinner prep for Donna. She comes up with a dish to make and then sets out the ingredients to be cut. I cut the ingredients and usually will place them on a quarter-sheet pan and she can use them as she prepares our meal. She calls me her sous-chef, but I hardly qualify for that title. I think I’m more like an amateur prep cook. Last night I was getting ready to cut potatoes for Donna – she was making potato salad to go with the Memphis-style babyback ribs I had in the Traeger smoker-grill. I asked her how she wanted the potatoes cut. She said “Let me show you.” I handed her the Maboroshi nakiri – she never uses my Japanese kitchen knives – she was amazed at how it split the potato with no effort at all.

While I’m on the subject of sharp, shiny objects, I want to talk about something I’ve been thinking about for a long time. I wrote a post a few years ago about the shaving razor business model where some companies will give you the razor handle to get you on the hook to buy disposable plastic razor cartridges from them. This model took hold back in the 1970s and the marketing machine has convinced us that we need two, three, five or more blades in the razor cartridge to get a decent shave.

I remember the razors my dad and grandpa used – they were called double edge safety razors. No plastic. I’ve read that the EPA estimates over a billion plastic razor cartridges end up in landfills every year in the USA. That’s a lot of plastic bits.

I’ve found there’s a cult-like following for shaving the old-fashioned way with a safety razor or a straight razor – it’s called wet shaving. No more plastic disposable junk – with ever escalating replacement costs. With a safety razor or straight razor, you pay up front a one-time cost for the razor. With a straight razor you need to develop sharpening skills (or send it to a sharpener), but there are vintage straight razors on the market that are 100 years old! With a safety razor you still need blades, but they are ten to twenty cents a piece and they are recyclable metal – no plastic. Again, these razors can last for generations.

There are forums such as Badger and Blade where you can learn how to wet shave and what equipment to buy or avoid. There are also countless YouTube videos. I jumped aboard this train. I went head first and bought a straight razor.

Ralf Aust 5/8 straight razor

I bought a Ralf Aust 5/8 straight razor. Ralf is a craftsman in Germany running a one-man shop assisted by his wife with the bookkeeping and shipping. The photo didn’t pick up the laser engraving on the blade – it says “Solinger Handarbeit.” This translates as “Handcrafted in Solingen.” The scales (handle) on this model are made from redwood.

I have plenty of sharpening stones and some sharpening skills. A straight razor is different from a kitchen or pocket knife though. The techniques are similar, yet different.

For one thing, razors need to be finished to a higher level of refinement than a knife. Most people prefer a certain level of “toothiness” in a kitchen or pocket knife – unless they’re cutting sushi. A truly razor-sharp edge might not “bite” into a tomato or pepper skin. This toothiness would make a shaving razor very uncomfortable.

So, I needed a finishing stone for my razor. I wanted go natural, so I bought a rectangular Belgian coticule finishing stone with a small bout – called a nagura in sharpening circles.

Belgian coticule

The Belgian coticule is a whole story by itself – it will have to wait for another post.

You also should have a couple of strops on hand for a straight razor. These used to be common items in barber shops. I now have two hanging strops – one made in Germany from linen and one made in Morocco from cow hide.

Well, shaving with a straight razor is not straight forward. It’s scary! Putting a razor sharp blade against your face is daunting. It takes skill to successfully shave with it. Acquiring that skill can be a painful experience. After a few bloody experiences, I decided I needed to take baby steps. It was suggested on the forum to start by only shaving the easy parts – your cheeks – until you get a better feel for it.

If you know me, you know I also shave my head. This would be impossible for me to do with a straight razor – what was I thinking? I’d probably cut my ears off!

Well, I really wanted to ditch the disposable cartridge razor. So I ordered a safety razor. That’s a whole ‘nother topic with much to learn – but it’s not nearly the learning curve of a straight razor. I call it my training wheels – I can shave my cheeks with the straight razor, then shift to the safety razor to finish my neck and touch up areas. I can also shave my head with it. High quality safety razor blades can be obtained on the internet for about $10 for 100 blades.

Goodfellas’ Smile Bayonetta safety razor

My safety razor is made in Italy by Goodfellas’ Smile. The model is Bayonetta and it is CNC machined from brass. It’s a little aggressive, I have to be careful shaving my head. But I’m enjoying the process and I understand the reason why guys and gals do this. That’s probably enough about sharp, shiny objects for now – I’ll be revisiting this sub-culture topic.

I only have one dinner plate photo for this post. Not that Donna hasn’t made many photo-worthy dinner plates, I’ve just neglected to photograph them. This is one-pan tortellini with sausage and fennel soup.

Chopping the fennel was interesting – the recipe used all of the parts. I thinly sliced the stalks and bulb, then minced the fronds. It was an excellent dinner!

My last tennis lesson for the season was a couple of weeks ago. We’ve been playing some informal pick-up games. Summer play will begin tomorrow. I played pickleball for a couple of hours yesterday and I think all of the tennis has actually improved some aspects of my pickleball game – I was on fire despite not playing recently while I concentrate on tennis.

The weather has been great. A little on the warm side, but mostly comfortable. We’ve had highs in the upper 70s to 80s. A 90 degree day here and there and more 90s to come. I’m not complaining.

The snowbird season is coming to a close. Many of the winter visitors at Viewpoint have departed for points north. Golf league and tennis league play has ended and I had my last tennis lesson of the season.

Donna and I intend to continue to play tennis through the summer in the mornings with other full-time residents. My goal is to become proficient enough to join a team in league play in the fall. I held my last pickleball class of the season at the end of March.

Donna found information for free admittance at the Desert Botanical Garden in Phoenix on the second Tuesday of the month. So this past Tuesday, I grabbed my camera and few bottles of water and we headed there. We arrived around 9:30am and I was surprised at the full parking lots. We parked in the overflow lot and got our second surprise at the entrance. At the check-in area, we were asked if we had a reservation!

I thought this was really odd – like needing a reservation to visit the zoo or something. We told the guy we didn’t have reservation and it didn’t seem to matter. He just handed us a map and waved us in. We entered and it felt like we were at Disneyland. The walking paths were all crowded and little kids were everywhere. I brought my camera thinking I would be able to photograph birds in the gardens, but with all the people the birds seemed to have fled to the open desert.

We walked around for a bit, but it was like going down a crowded Walmart aisle. Oblivious people would stop in the middle of the path, blocking others from moving through. I shot a few pictures of flowers, but we soon tired of the place and left. I would not have been happy if we had paid for admission.

I wrote about a new natural whetstone I bought in my last post. Like most things I do, I had to take it up a notch. I enjoy sharpening knives – I find it almost meditative and doing so on natural stones adds another element to my enjoyment. The use of stones for sharpening tools by humans predates any historical reference. Homer wrote about Cretan whetstones in The Iliad and Odyssey more than 12 centuries ago.

The truth is, natural whetstones are harder to use than man made synthetic whetstones. The biggest difference is the consistency of the stones. Modern synthetic whetstones have abrasives that are usually some form of aluminum oxide or silicon carbide. These abrasive particles are uniform in size and shape and are held by a binder that wears down and constantly releases fresh abrasive particles. The stones are engineered with different binder compounds that can be relatively soft or hard.

Natural stones on the other hand are cut from various types of rocks. They are quarried or mined from seams of mostly homogenous stone types that are naturally abrasive. The abrasive particles are randomly distributed and are bound together with other natural compounds that have fused together from heat and pressure over millions of years. These stones are found and mined all over the world, but the most desirable stones originate from Japan, Belgium and Arkansas in the USA. There are many other lesser known stones from other countries.

The Japanese and Belgian stones can be very expensive – some are considered collectible. I didn’t want to go down that rabbit hole, so I sought out lesser known stones like the Indonesian stone I wrote about before. I bought two more Indonesians – a medium and a medium/fine to go with the fine stone. These stones are called Red Stone (Batu Beureum in Sundanese – the language of West Java), Black Stone (Batu Hideung) and White Stone (Batu Bodas) respectively.

Red, Black and White Indonesian whetstones

I don’t let my Japanese kitchen knives get very dull, so these three stones are a good progression for sharpening them. If the knives were very dull or chipped, I would start with a soft, coarse synthetic stone. I would do the same if I was sharpening a softer stainless steel knife like a German Henckels or Wusthof.

I took things a step further and added a couple of fine finishing stones. The first one is Japanese – an Ocean Blue Tsushima whetstone. Tsushima stones come from two mines – one on a mountain on Tsushima Island – these are usually brownish – the other mine was under the ocean off of the coast of Tsushima. These are black or dark blue. The mines closed in the 1980s, but there are still plenty of stone blocks available.

Very fine Tsushima whetstone

The other finishing stone came from a mine on Velky Rozsutec – a mountain in the Mala Fatra range in Slovakia. These stones are favored by farmers in that part of the world for sharpening scythes and for knives. The stones were mined and cut by one man until his passing in 2013. A few years later, his son and daughter took over the business and began cutting and selling whetstones.

Rozsutec whetstone

Rozsutec stones are unique. They are cut from a very hard strata of sandstone. I usually think of sandstone as a soft, crumbly type of stone. Not these. They are very hard and long wearing stones. The silica grains cut the metal when sharpening. Over time, these grains don’t release, they slowly flatten and the stone get smoother. At some point it needs to be conditioned by flattening the surface with a harder stone or diamond plate to expose fresh grit.

I use the Tsushima and Rozsutec in the final stage of sharpening. These require a very light touch and can provide an extremely keen, razor-sharp edge on hard steel. I used all these natural stones on my Sanjo sujihiki ( a Japanese slicer blade) and got a very fine edge. When I used it to cut a pork tenderloin, it practically fell through the meat. As an experiment, I held the blade between my thumb and first two fingers and slid the 240mm blade across the tenderloin with no pressure other than the weight of the blade. It cut cleanly through!

For the past several weeks I’ve been striking out on astrophotography. The nights have been either cloudy or the targets were too close to nearly full or bright full moons. When I shoot from the east tennis court lot here at Viewpoint, my preference is to locate targets that are in the north or east. This keeps me pointed away from the worst of the light pollution, but it’s still a light polluted sky.

Last week I caught a break. I set up on Tuesday night, March 2nd, but was stymied by technical problems (software). I went back out on Wednesday and was able to begin imaging a little after 8pm. I shot 80 exposures, 90 seconds each and packed up. I knew it wasn’t enough – I was targeting a very distant and dim galaxy – the Needle Galaxy (NGC 4565). This is an edge-on galaxy around 40 million light years away from earth.

A week later I had favorable conditions and went after it again. I repeated my earlier effort and picked up 80 more exposures. I used my Astro-Tech 115EDT telescope with a 0.8X reducer/flattener. This gave me a focal length of 644mm and an F5.6 aperture – you photographers out there will know what I mean. I try to keep exposures under 90 seconds in the heavy light pollution – preferably 75 or 60 seconds. This galaxy was so dim, I knew I needed to push the envelope and F5.6 allowed me gather enough light at 90 seconds.

My APM 140 with a focal length of 980mm would have been a better field of view for this target, but at F7 I think I would need a lot more time on target. It worked out better than I expected with the AT 115EDT.

If you click on the photo above to enlarge, you might be able to find three more galaxies in the image – they are much farther away and small.

As usual, Donna is feeding me well. Here are a couple of typical dinner plates from the past month. I bought a USDA Prime tri-tip at Costco and smoked it on the Traeger smoker/grill. Donna served it with sweet potato and green beans.

Another meal was simple grilled chicken seasoned with salt and pepper served with grilled peppers and onions with feta and grilled bok choy.

The weather for the past month has been a little strange. We’ve had very pleasant stretches with highs in the mid-70s, but also had rain at least one day per week accompanied by a couple of cool days with highs in the low 60s. It seems like that’s all in the past now. Today the forecast calls for low 90s. The next two weeks call for highs ranging from the mid-70s to 80s and sunny skies.
