History, mentionings from the forums etc.

In this post on the Spyderco.com forum, from 30 March 2022, Sal Glesser shares a story about MBS-26 while touring the Masahiro factory: Many years ago, we were touring the very impressive Masahiro factory. I asked Koji, the President, why his Daido made proprietary MBS-26 was able to punch so high above it's weight? He said they followed the meticulous heat treating instruction provided by Daido. This included heat treating in lead pots, which I watched. The secret" knowledge of the blade industry never ceases to amaze me.
