Come by our forum in 2 weeks for the K20 sword pre-order do-over (I'll get enough material for up to 300 swords this time, lol).
What is a ninja sword?
I'm glad you asked.
I have no idea...
Believe it or not. Some aspects of our heat treat are actually not completely 100% totally easy to do perfect every time and the swords were especially challenging.
In this situation, the steel for one heat, 32 swords, was exposed to oxygen at a temperature where we lost some of the carbon on the skin of the steel in a process called decarbonization. It was a minor error and the damage was shallow but still significant. Some of those are salvageable. This sale is for the last 5 of them that will be available here.
Historical swords were made with lower carbon steel cladding on the outside to prevent them from breaking in hard impacts. This is because (gasp) the steel that historical Japanese swords were made from was actually TRASH, which is what necessitated the development of their outstanding forging skills and techniques. Our steel, on the other hand, is the best in the world and does not need a soft cladding for phenomenal durability. Our steel doesn't break and would cut those historical swords in half. The lower yield point on the decarburized surface makes the sword take a set sooner during a harsh bend and is not something I want on my work.
So, as a way to salvage these swords and get them into the hands of you high quality hooligans, we have ground the edge back .030" and also ground the primaries and the flats down into good steel. Areas that do not lend themselves to grinding have been chemically etched back. I can say with confidence, these swords are 100% up to any task you want to press them to.
$1,600.
