The general consensus, of myself and those who got a knife from the first run, is that M4 at 63.5 Rc takes and holds a great edge.
Since I started with 3/16" stock, those blades tended to be around .160" thick or more.
This seems a little thick for day to day field work on animals, etc and thinner would make better for slicing and cutting blades.
I contacted Niagara Specialty Metals and they have some .140"-.156" thick M4 in a 24"x36" sheet they are holding for me
to decide if I am going that route.
I would be focusing on various patterns I already make with blades in the 3" to 4" range and .125" thick.
I also will be open to special requests and make a knife to your pattern/request..
Several have asked to be on the next M4 list (if it happens) and I will finalize with them as time is appropriate.
I will try to use all the steel I get in one or two heat treats, so some up front planning/commitment is necessary.
Let me know if interested in being part of this run.
I would prefer to be contacted here and will not be advertising on any other web site at this time.
Thanks
