About Hado Sakai Sumi - This Sumi line is an exciting collaboration between HADO and Knifewear. They approached us looking for new ideas and loved our design suggestions: black ‘kurouchi’ surface with a nicely polished ‘spine,’ or back of the knife, and ‘choil,’ as the junction of the blade and handle is called by knifenerds. The result is a knife that feels incredibly refined while maintaining a rough, handmade aesthetic. The traditional white carbon steel requires care to avoid rust but gets blazingly sharp—seriously, it’ll blow your mind the first time you use it.

The single piece of oak used for the handle is an excellent addition to the knife; it feels great in hand and looks stunning.

While the blacksmith handles the forging and hardening to ensure the knife keeps a crazy sharp edge for a long time, the sharpener uses their mastery of steel grinding and polishing to turn a raw piece of forged steel into a precision tool.

Maruyama-san of HADO is one such master sharpener. HADO sources blades from the best blacksmiths in Sakai and refines them into kitchen scalpels.

About the Shape - The Ko Bunka is a smaller version of a Bunka. Any guesses on what “Ko” means in Japanese? You nailed it! It translates to “small.” This little knife is awesome because it still gives you knuckle clearance on the cutting board. Making sure you can mince garlic and comfortably chop veggies. A badass love child of the Bunka and Petty knife, it works for smaller jobs in the hand or as an all-purpose blade.

A note about measurements: Knife edge length is shorter than stated, as Sakai knives are measured from the front of the handle to the tip. Additionally, some knives feature a small 'machi' gap between the handle and blade.

Knife Care

A NOTE ABOUT RUST  

Carbon steel is an awesome material to make knives out of. It’s easy to get sharp and stays sharp a very long time. But this comes with a trade-off; It will rust if you let it. To  avoid “bad” rust (orange rust) Wipe the knife dry with a dry cloth after use. Over time, 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.
