Japanify: Sharpening Carbon and Stainless Steel Knives

hōchō After seeing how well the chefs (at Konohana, the sousaku-ryori restaurant I worked at last year in Tokyo) and the housewives in Japan take care of their hōchōs (Japanese cutlery), one of the first things I did when I moved back to the U.S. was to get a knife sharpener for my carbon-steel hōchō I purchased in Kappabashi two years ago. Luckily, a Japanese knife and tool shop called Hida Tool & Hardware Co., Inc., is a short, less-than-10-minute walk from my Berkeley apartment. The staff showed me a range of water stones that would be ideal for my hōchō and my budget ($50). I ended up purchasing a 1000 grit water stone for $40. If I win the lottery, I hope to invest in a 3000-6000 grit stone (priced at about 3-5 times that of a 1000 grit stone) for a superior, fine finish. Water Stone 1000 grit The staff person at Hida Tool took me to the back of the store for a quick demonstration of how to use the water stone for sharpening, which proved very helpful. After sharpening my knife once a week for the past 2 months, I am finally getting the hang of it - using not just my hands and wrists but my whole torso to propel a motion that seems less stressful for both me and my knife. Here's how to sharpen a steel-based knife on a water stone. 1. Soak water stone for 2-3 30 minutes. Water Stone 1000 grit 2. Place stone on a wet towel for stabilization. 3. Sprinkle some water on the stone. 4. Sharpen the knife at a 15 degree angle. The Hida Tool knife sharpener said that should be equivalent to stacking two quarters on the non-sharp edge of the blade. hōchō sharpening 5. With the blade edge towards you, push the knife away from you at the 15 degree angle. Apply firm but not immense pressure as you push it away from you. Repeat in a rhythmic motion. Once you feel the curled metal of the blade edge, flip the knife over. hōchō sharpening hōchō sharpening 6. With the blade edge away from you, pull the knife towards you at the 15 degree angle.

Inspect your beautiful work and test out on a piece of paper (no cardboard) or food. hōchō hōchō 8. DO NOT clean the water stone after use. The clayish "mud" should be left alone to dry. These fine particles will improve the sharpening performance of your water stone. REVISION: I had the Hida Tools knife master Chika-san review my article and she said to clean the water stone after use. What she did say was to NOT clean it while you are sharpening the knife. Deep apologies for the misinformation. Water Stone 1000 grit

  • Apologies, Yamahomo! I confirmed with the Hida Tool person about step 8. You SHOULD indeed clean the stone after use. What she did advise me (and I think what I mistook that information for) was that you should not clean it at any point while you are sharpening. Please see my revision for step 8 in the post.

  • If you are a beginner in using a chef knife, do not get a Japanese Carbon Steel knife. They chip and rust if not taken care of properly and used correctly.

  • It is also able to respond quickly to a honing rod should you need it to.
    They had a thick layer of soft and ductile steel
    surrounding the core, so that the hard steel is only exposed at the cutting
    edge. Its layout tends to make it specially beneficial for thinly
    slicing veggies.

  • Ahh I’m still surprised nobody posted any knife stores in LA. Well there is a store in Little Tokyo called Anzen Hardware on 1st Street. They’ve been there for almost 40 years. Many local chefs go there.
    1) If you are using a carbon steel knife, after drying it, put a layer of vegetable oil. If you have a stainless steel sandwiching carbon steel edge, it’s still safe to put a layer of oil on entire knife, not just the cutting edge.
    2) Don’t wash the stone while sharpening a knife, because the black grit is a polishing grit which you use it to sharp the knife.
