About Masakage Koishi -

These blades are thin and lightweight but substantial enough to fly through vegetables with ease. I love how most of the weight is focused on the business end of the knife, which is made from some truly remarkable steel. Kato-san forged this knife from Aogami Super, which gets shockingly sharp and keeps an edge for longer than most. The undisputed king of knife steel in my opinion.

The ‘tsuchime’ (meaning ‘hammered’) and ‘kurouchi’ (meaning ‘black hammered’) finish gives the impression of river pebbles, inspiring the name Koishi (meaning ‘small rocks’). A true culinary badass, like Jason Momoa in kitchen knife form.

Yoshimi Kato is the son-in-law and successor of Hiroshi Kato, one of the founders of Takefu Knife Village. The transition from apprentice to master blacksmith and company head has been seamless for Yoshimi-san. He tells me that he strives to continuously improve his skill day-by-day, and I look forward to working with the next generation of Kato for decades to come!

Yoshimi-san is a quiet man, calmly pushing forward at a steady pace and speaking more through his knives than his words. And boy, do they speak! Yoshimi-san’s knives are among the most gorgeous, laser-like blades I’ve ever handled.

About the Shape - This is the knife for smaller jobs that are done on a cutting board. Perfect for slicing shallots, cutting herbs, and boning smaller proteins. Additionally, Petty knives are an indispensable tool for those who feel uncomfortable wielding a larger chef knife.

Knife Care

Carbon steel gets crazy sharp and holds an edge very well, but can rust. Stainless steel has the benefit of being less prone to rust but isn’t quite as sharp. Luckily, Japan has the solution. They make lots of kitchen knives by sandwiching 3 layers of steel together. In the case of kitchen knives the softer, outside layer is stainless and the hard core is carbon steel. The best of both worlds, super sharp — with low hassle. These are some of the most popular knives we sell. The exposed core steel can rust, and you have to wipe it dry to keep that from happening, but this is only a small part of the knife. Over time, the edge will oxidize from from shiny to a dull grey, this oxide layer slows down rust.

USE

• Only cut food you can bite through with this knife. Hard foods can chip the blade. No olive pits, bones, lobster shells, woody stems or parmesan rinds. Cutting frozen food is especially bad because the cold will make hard steel even more brittle. If you wouldn’t chew it with your own teeth, don’t cut it.

• Your cutting surface is the biggest culprit of dulling your knife. Use wood. End grain wood is especially good. Plastic can be fine too, but certainly not glass, granite or bamboo.

• The edge of your knife works best sliding forwards or backwards. Scraping the knife edge sideways will dull or damage the edge. Instead, use the spine of the knife to move foods across the cutting board. Do not twist the edge or pry with the edge, this is the worst screwdriver you ever bought and these motions will certainly damage the edge. Listen to the knife! If you can hear the edge making a “tink” sound on the cutting board, change what you are doing.

CLEANING

• After use, wash the knife by hand with regular dish soap, rinse with hot water and dry by hand immediately. Dishwashers are very bad for knives.

• Wood handles may dry out over time and exposure to water. Simply treat them with some food safe mineral oil or beeswax.

• If you see orange rust, remove it. The scrubby side of a sponge can do the trick. If it’s still not coming off try baking soda and water mixed into a paste or a product called Barkeeper’s Friend.

STORING

• Protect the edge; for your safety and to avoid edge damage. A simple blade cover will do the trick if you keep knives in a drawer or travel case.

• A convenient wall magnet made with wood is a great way to show off your knives. Be sure to put it back spine first, then roll it onto the blade face. This will keep the edge from contacting the wood first.

• The good-ol’ counter top block can keep knives at the ready and protected. So can drawer inserts. Whatever the method, keep the edge from touching anything else.
