About Masashi Kokuen -  This blade's core is made from hard SLD steel clad in softer stainless steel, which Masashi-san can push to the absolute limit of hardness through his impressive skill and a couple of top-secret techniques. In plain English, this means they keep a crazy sharp edge for a long time but are much lower maintenance than traditional carbon steel blades. He sharpens blades in a unique way, making the back end more robust for chopping and the tip more precise for delicate work.

The dark finish of the Kokuen gives its name. Meaning ‘black smoke’ in Japanese, the Kokuen is inspired by the atmosphere of Masashi’s workshop.

First training with his brother at Yoshikane, then striking out on his own, Masashi Yamamoto relentlessly pursues the creation of a perfect knife using the traditional techniques passed down in his family and augmented by a modern understanding of metallurgy. He’s also a certified badass, forging in flip-flops and lighting cigarettes off red-hot steel like an 80’s action hero. 

About the Shape - “Sujihiki” translates to “Flesh Slicer” and it does exactly what the name suggests, perfect for carving and slicing roasts, turkey, raw meats, fish, and all other proteins and the extended blade length allows you to slice with one long stroke, instead of sliding the knife back and forth in a sawing motion. Making clean slices of brisket or ultra thin applications like Carpaccio a breeze to execute.

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


A NOTE ABOUT RUST

Semi-stainless steel is a compromise between the edge retention of carbon steel
and the rust resistance of stainless. This steel will rust if you let it. To avoid “bad” rust (orange rust) Wipe the knife dry with a dry cloth after use. By this we mean: between cutting and putting the knife down, wipe it dry. Overtime the blade will begin to protect itself with an oxide layer (grey to dark grey “good” rust), this will slow the reaction time but not inhibit the rust entirely. Maintain the good habit of drying off your knife.

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.

Perfect slicer

"This slicer is simply outstanding, it has an impeccable balance, glides through ingredients effortlessly, and its design is absolutely stunning!"

— Sylvain D. (5/5)

It was the Star at Thanksgiving

"We used this knife to carve our turkey at our office Thanksgiving luncheon. It was the star of the show. Beautiful and sharp, it made short work of a 24-lb turkey. Thank you, Knifewear!"

— Elizabeth S. (5/5)

Superb Knife for carving and slicing

"The title says it all. The knife is a joy to use and as capable of a super slim slice as your knife skills allow."

— Roger R. (5/5)

Sharp as

"I got a gift card, and looking for something different than my collection I was after a "racecar" of a knife. I asked to look at a bunch of sujihikis, ranging from makers and steels. This thing stole my heart, it's so so crazy thin and crazy light. Walking through the farmers market and seeing chunks of boneless meat is a bit of a problem. I went in looking for a racecar and I came out with a Japanese sport bike. The power to weight outpaces everything I've got. It's so unbelievable to whip around and fly through meat. The website doesn't do this thing justice, go see it in person!"

— Callum (5/5)

Amazing

"I bought this and the Nikiri from the same line and they’re my new favourites. Beautiful polished edge, very light and cray cray sharp"

— Stuart C. (5/5)
