We (UK based) all chip in for a batch order and split the shipping???
Thanks @D_W the information and your explanations are very valuable. We woodworkers do tend to get ripped off by these tool salesmen / makers who make unsubstantiated claims about how great their steels are! You have proven this not to be the case and there is the proof a decent steel is out there for ALL budgets to benefit from. Thank you sir and well done!
it's hard to know what the right answer is with this stuff. I don't think most woodworking tool companies are that much interested in the steel - it's just part of the tool. LV went through a long selection process to pick what they're using now (V11) and they don't really want anyone to know what it is, at least not as public information (it's expensive, anyway, I don't think anyone else would use it, but importers could use cheap stainless steels and claim to be using it).
I don't have a furnace, which I think I'd need to get AEB-L right, but I do have AEB-L - it's a little more than this stuff, but cheaper than ground O1.I can make an iron good enough with it just in a forge to test its edge life (1.6 times that of O1), but not hard enough that I'd give one away for someone to play with.
Maybe I'll try again at lunch - heat treating stainless in a forge is sort of a forbidden practice, but I think the only thing I'd need to get it harder is a liquid nitrogen dewar - maybe in the future. I've got some ideas to get halfway there just with a small forge and a freezer with ice buildup on the sides.
