    About Hatsukokoro -The Hatsukokoro series encompasses a wide range of knives, forged and crafted by some of the best knife makers in Japan. They work with a wide variety of artisans, from blacksmiths to knife sharpeners and handle makers. By working with folks who have mastered their craft, each aspect of the knife is carefully curated.

    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 and “gyuto” even translates to “cow sword”. If you want one knife to do it all, This is it. The longer blade typically gives the blade a forward balance that allows it to work for you. While the blade would ideally by slid forward or back while cutting, they are also great for folks that prefer to 'rock' their knife while cutting.

    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.
