About Masashi Kaijin - The blade's core is made from hard VS1 steel clad in softer stainless steel. Through a special heat-treating process, Masashi-san can make VS1 incredibly hard, giving it edge retention on par with high-end carbon steel. He sharpens blades in a unique way, making the back end more robust for chopping and the tip more precise for delicate work.
The textured appearance of the Kaijin gives its name, which translates to ‘ash’ and references the traditional forging process Masashi uses. Normally blacksmiths must overheat the knife to achieve this sort of finish, which can tamper with the knife’s quality, but Masashi-san is able to do it in a controlled, low-temperature way that doesn’t affect the steel.
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 - 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.

"Love this knife. One of my favourites. Sharp and good weight on the overall knife. Cuts like its going through butter. Also looks awesome. I love this style of finish. I now own several other Masashi Kaijin knives."
"Elegant but not so much that I don’t want to use it. Nice wide top for a good grip and it doesn’t flex. Blade is very sharp and only takes a few strokes with a rod and strop to keep it so."
"The weight and build of the knife is substantial, and it exudes confidence when held in hand. The craftsmanship is remarkable, and I am delighted to look at it and use it in the kitchen."
"I rly love this knife. Very sharp but not too delicate tho and absolutely beautifull. Even more so than the kokuen imo. I highly recommend it :D"
"This is my first hand forged Japanese knife and I decided on this one after reading about Masashi and I'm so glad I did. It's the sharpest knife I own by far and it looks so good I had to display it on a magnetic holder where it can be seen. It feels good in the hand and definitely makes cooking easier. Now instead of thinking "I have to go cook" I think "now I get to go use my awesome knife!" The only problem is there's room on my magnetic holder so I guess I'll have to buy a couple more."
"Despite that reference, on the usual Workhorse-Laser spectrum, this is definitely the former. A thicker spine and forward CoM makes the blade feel heavy in the hand, which you can use to your advantage to motor through prep when you find your rhythm. You'll find it start to wedge with something like cabbage, however it is pretty thin right behind the edge. Perfectly combined with low (but not zero) maintenance core steel and you've got a really dependable beast of a prep knife that you're not too worried about wiping clean after every half of an onion. Finish is beautiful and feels great in the pinch (especially if things are getting slippery) but not so flashy that you'll be attacting unwanted attention. But then, someome walks past your station and catches that Nashiji in the light..."
"This knife is amazing! It's so sharp, it's really upped my game in the kitchen. Probably the most beautiful knife I've ever owned as well. Love my purchase."
"Handles very smoothly. A great everyday work horse of a knife. Solid performance. Handle is comfortable to use and feels great. Easy to maintain the edge, and takes a wicked sharp edge everytime it's touched up."
"Great store and staff. Helped me pick out the perfect knife."
"Awesome service as usual. The knife is amazing!"
