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 also a multi purpose knife, but with a slight vegetable bias. Santoku means 'Three Virtues' or 'To solve Three Problems'. The virtues or problems are slicing, dicing and mincing. Santoku is usually found in 160mm - 190mm lengths. These are more and more popular in Western kitchens due to the unique shape and smaller easy to handle size.

A note about measurements: Handmade Japanese knives can vary in their dimensions, so these measurements are only an example.


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.

Reviews

Light and sharp

"Very light in the hand. Great blade feel. Very effortless slicing strokes. Carbon steel hasn’t been hard to care for with a quick rinse and wipe. Customer service at Knifewear was great."

Alasdair M. (5/5)

It was a gift

"I didn’t get to use it as it was a gift. The sales associate (Rachel maybe??) was awesome! She was so patient with me and had soooo much information answering every question! The knife was so nice, I even bought the book LOL! Can’t wait to buy one for myself!"

Kelly c. (5/5)

Koishi Santoku - a welcome addition

"The Koishi Santoku is the third addition to my Koishi collection. It soon becomes my knife for most jobs except the ones with special needs. As like its siblings, it is razor sharp and beautifully finished. Special thanks to Binh An who showed me multiple knifes from different makers and explained the differences."

"Sharp,light,comfortable, has that traditional japanese feel and looks badass!"

Carlos c. (5/5)

Great santoku

"I picked this out from Knifewear in Ottawa. Staff were very helpful with finding me just the right knife. Took it home super sharp and the aogami super blade has been great - stayed sharp and no issues with corrosion (it has received proper care of course). Highly recommend!"

Daniel J. (5/5)

Favourite knife

"I used this knife primarily for cutting fruit, prepping veggies, cutting raw meat. The edge is amazing; we thought our existing knifes (which are decent quality and sharpened to 15 degrees) were good, but this is a whole different world!"

Neil B. (5/5)

Q&A

This knife says it has a blade height of 41mm. Is that so? It seems like it should be more like 47mm. Am I wrong?
Hey there, good catch, it is more like 47mm! - Ellie
What is the case it comes in made of? Do you have replacements if mine gets damaged?
Hey there, it only comes in a rice paper / cardboard box. If you need to grab a case, I would recommend one of these [blade guards](https://knifewear.com/products/knifewear-blade-guard-200mm).
