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.

"Very easy to handle,super sharp"
"Most people are reluctant to pronounce anything “perfect” but I can’t imagine how one would improve this knife. It is easy to use, ridiculously sharp and extremely comfortable in the hand. It’s a pleasure to slice a tomato to a thickness which is almost transparent and not have the blade slip on the skin. A simple wipe with a paper towel, with the fingers carefully out of the way, takes care of any alarm concerning rust problems. Love using it."
"This is an awesome small kitchen knife. Light in the hand and cuts so finely. A great companion to my Koishi Ko-Bunka. Love them both!"
"So exciting, I knew the second I took it out of its box. It felt wonderful. It is small, light, very sharp and lovely. It is the perfect size for my small hand. Do I mind rust prone? Absolutely not. I put my designated knife cloth where I’m working. Takes not a second to keep my knives clean and dry. This knife is so serviceable and has become a kitchen favorite."
"I returned the knife because it was to small then ordered the 120mm."
"I ordered this Masakage Koishi Petty 75 based on my experience with my Koishi Santoku. I love the balance of these two knives. They feel like extensions of my hand. I ordered online and waited about 3 months to get the Petty sight unseen. Worth every penny."
"I am so happy that this knife is finally here. It complete and for fills what I want and need in the kitchen. I couldn’t be happier with Knifewear’s and there products"
"This little charmer has become my “go to” for all the little jobs of peeling coring and small dice to just begin. It fits my hand well, and I love the finger guard. A great knife!"
"I have couple of dozens japanise knifes. This one is awesome, really handy, great tiny laser. But. With this one I finally decided that all in all I prefer stainless steel especially for such a specific knife. This small petty started to rust pretty soon, and of course I easilly fix it. But its a bit annoying constantly clean and dry it while its purpose is small quick jobs that you do here and there between using bigger chef knifes."
"Great little knife, super sharp and beautifully crafted. Would highly recommend."
