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.
About the Shape - This is also a multi purpose knife, but with a slight vegetable bias. Santoku means 'Three Virtues' or 'To solve Three Problems'. The virtues or problems are slicing, dicing and mincing. Santoku is usually found in 160mm - 190mm lengths. These are more and more popular in Western kitchens due to the unique shape and smaller easy to handle size.

"Very light in the hand. Great blade feel. Very effortless slicing strokes. Carbon steel hasn’t been hard to care for with a quick rinse and wipe. Customer service at Knifewear was great."
"I didn’t get to use it as it was a gift. The sales associate (Rachel maybe??) was awesome! She was so patient with me and had soooo much information answering every question! The knife was so nice, I even bought the book LOL! Can’t wait to buy one for myself!"
"The Koishi Santoku is the third addition to my Koishi collection. It soon becomes my knife for most jobs except the ones with special needs. As like its siblings, it is razor sharp and beautifully finished. Special thanks to Binh An who showed me multiple knifes from different makers and explained the differences."
"Everything about this knife is great. Looks, feel, weight, balance. Staff were knowledgeable, helpful, friendly. Great knife and experience."
"Recently bought this knife as a gift for my partner who only used western knives before. We both really love how enjoyable this knife is to use daily. Form its sharpness, light weight, idela size and extremely comfrtable handle, we have no hesitation in giving this blade 5 stars!"
"Sharp,light,comfortable, has that traditional japanese feel and looks badass!"
"I picked this out from Knifewear in Ottawa. Staff were very helpful with finding me just the right knife. Took it home super sharp and the aogami super blade has been great - stayed sharp and no issues with corrosion (it has received proper care of course). Highly recommend!"
"I used this knife primarily for cutting fruit, prepping veggies, cutting raw meat. The edge is amazing; we thought our existing knifes (which are decent quality and sharpened to 15 degrees) were good, but this is a whole different world!"
"I purchased this as a gift for a loved one and they are besides themselves with joy. Fantastic service and advise from Knifewear gave me the confidence to make the purchase. Thanks!!"
"I’m thankful to have come across Knifewear online and on YouTube. Their website offers a lot of information about their company and the products they sell while their videos on YouTube are very good also. Overall I think Knifewear is a very good company. Alohað´ð:male_sign:ðª"
