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 - Inspired by the profile of a traditional European chef knife, Gyutos are a multi purpose knife with a slight meat cutting bias. “Gyuto” translates to “cow sword.” If you want one knife to do it all, This is it. Starting at 180mm, Gyutos can reach the ridiculously long (and awesome) 370mm. For the at-home or professional cook, we recommend a Gyuto which measures between 210mm and 270mm long.

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

This Knife Has Main Character Energy

"Absolutely love this knife. Super sharp, light, holds an edge forever, and looks badass. Aogami Super is just perfect."

— Steve C. (5/5)

Now its a month old. . . . .

"Have sliced, diced, julienne and brunoise about 150lbs of veg and another 70bs of meat and fish. Still as sharp as when it first arrived. Took a patina right away and even tho i frequently forget to wipe it, it hasnt had any rust. Its an absolute pleasure to use. I just had to put in this updated review. I know the tomato slice clip is kinda cheesy but after this much use my other knives just dont hold an edge this well. I havent sharpened it at all, this is the factory edge"

— Shane N. (5/5)

Knifewear. com is superb!

"This is a sweet knife. Besides being visually pretty, it slices smoothly through everything I've thrown at it so far and the edge is still razor sharp. I like that it is stainless clad with an aogami carbon steel edge cuz it gives me the best of both worlds. The octagon handle is perfect for my hands and the service from the knifewear. com people (i phoned in twice with a lot of questions!) has been fantastic. I do some private catering, cooking for some camps etc and as a father of 7kids who eat enough to keep a grocery store afloat I really can appreciate a fine knife. My only problem is that i now need a petty and nakiri. I am waiting on a magnetic saya whenever knifewear. com stocks them."

Q&A

Why the significant price increase? It used to be in the mid 200s
Great question! Sadly most of our knives have gone up in the last couple years due to inflation, rising materials & transport cost, etc.
When will this come back in stock?
We should have them back in stock in the next while, being made by a blacksmith it can be tough to give you an exact date. What is it about this knife that interests you? We may have something available now that fits the criteria. You never know what we have up our sleeve ;) If you are set on this one we can always notify you when it is back in stock by signing you up for our notification system. If you'd like I can add you to it?
Hey there, the cherry wood handle on my gyuto appears to take on moisture easily during use. I am not sure if it's been finished with any moisture repellant. If not, what would you recommend that I use to apply on the handle to protect it from moisture?
Hey there! Because of Japan's humidity, they do not finish these handles with any sort of product. We find Clapham's beeswax to be the best solution, as it's foodsafe, moisturizes the wood, and seals out water! https://knifewear.com/products/claphams-bees-wax?variant=21827716382768
Good afternoon! Which Masakage koishi gyuoto sharpening stone should I buy ?
Hi Ruslan, I would recommend the [Knifewear 4000 grit stone](https://knifewear.com/products/knifewear-4000-grit-stone). It is a great all round stone for maintaining the edge of a Masakage Koishi. - Ellie
Does this knife come with a sheath?
Hey there, unfortunately not, we do have blade guards you can purchase with it!
