  • Wow, that knife blade was only 2.5mm thick? And it took that much to break it? That's impressive! And that last flat bar you tested was impressive too! One of these days, when I'm not completely broke, I'm gonna need to commission a sword from you. I especially like that you use 9260 spring steel. I don't know of anyone else who uses any silicon-alloy steels.

  • @RoninEnsse Cheers, I'll be here when the time is right :)

    Yeah it's tough steel (9260) and pretty well behaved. I like it.

  • @harumba2 Alright, that's good to know. :)

    I should correct myself, though. I know Cheness uses 9260 spring steel for some of their swords, but they only make Japanese swords, which I'm not really looking for.

  • @RoninEnsse Yeah and Chenness hype it up too much like it's some sort of super steel - they use it as a marketing gimmick. It's virtually identical to 5160 minus one element - a pinch of chromium to the 5160. It's just another good steel but only as good as the work put into it. 1060 will make a brilliant sword if it's treated right. And 9260 will be crap IF they treat it wrong.

  • Nice but I don't understand why you're braking the piece..???

  • @shadows503 Hi! To see the inside grain structure. To make sure there wasn't any grain growth or clumping when quenched from my selected quench temp. I found quenching from 870C to be best for my 9260 steel. The grain was still super fine like talcom powder. If it gets too hot the grain becomes visible and larger, like fine sand. This makes it weaker. I also wanted to see what it woult take and get a feel for how it sets. This was only a thin practice knife I forged and used for the HT tests

  • @harumba2 Yeah, I can understand that. I know heat treatment vastly important.  My interest in 9260 doesn't come from any such hype, though. I'm interested in it because of the silicon content, and the individual properties of that steel due to the silicon. I'm also interested in S5 tool steel for the same reason.

  • @shadows503 Pretty much, it was an experiment.
