Mugen HAP40

Knifewear Exclusive

Knifewear Exclusive

Mugen knives are exclusive to Knifewear and the Holy Grail of kitchen knives, in my opinion. Mugen knives are made with a super high tech new steel called HAP40 high speed powder steel, which can attain a Rockwell Hardness of 67+. In layman’s terms, it's insanely hard steel. HAP40 is one of the hardest steels available for knife-making and it provides amazing edge retention. It also polishes to a razor’s edge fairly easily, considering its hardness. Multiple layers of “suminigashi” steel give this knife its gorgeous look.

Made for Knifewear in Seki, Japan, these knives are the benefactors of 700 years of sword-making traditions. It was supposed to be impossible to manufacture a knife with a HAP40 core that’s clad with stainless Damascus steel, but the gentlemen at Mugen know how to make it happen. This knife started as a dream of mine, and now it's a reality! 

From the hardness tests we can see the treatment of the steel is very consistent and incredibly hard (67.4-68). The results are outstanding, showing the steel is incredibly fine grained and stable. These knives are probably the best performing knives I've ever seen; super sharp, incredible edge retention, and surprisingly strong.

The expertly crafted ergonomic handle made of black Pakka wood gives perfect hold and balance. Your hand will not get tired after hours of chopping and dicing.

Mugen translates to “infinity” in Japanese. Usually Mugen writes無限, but we chose夢限, which means “unlimited dream,” instead.
