The problem with higher alloy steels is that temp and soak times are critical to getting everything in to solution. There's really nothing too fancy, just time and temperature....but I highly doubt you get it just right with a charcoal forge until you gain alot of experience.
1084/1080 is hypoeutectic, so carbon content is not over saturated, meaning you really only need to get to critical temp and quench. Don't need a long soak, and it's very forgiving.
5160 is also hypoeutectic.
1095 is hypereutectic, has more carbon than naturally wants to dissolve in the steel. Have to force it with specified soak temp and time.

Thanks, mesophilic That's some really helpful info! yeah, I started reading about the difficulties of soaking accurately without a gas forge. I Think ill try 5160... and maybe 1084 or 1080. Is there much of a difference between 1084 or 5160 from 1095s as far as edge retention and whatnot?

My personal opinion is that any noticeable difference in those steels would not be easily achieved by a relatively inexperienced Smith in a charcoal forge, which is why I would lean towards the simplest.

Wait till we introduce you to air hardening steels and plate quenching ;D

You guys are on the ball, :) think I will just watch and lessen and stick to my old USA Nicholson files for now :) Love hearing it though, who knows, maybe I will learn and remember some of it. :) The more I hear the more I understand that you don't just fly by the seat of you pants like I do most of the time. ??? ;) :)

(lol) (lol) (lol) Yeah I’m learning that I think there’s more to steel then there is to bow making :fp
All the knifes I’ve made so far are with the method you just described pappy .... there not bad... what is your thoughts on your knifes edge retention and whatnot? Do you use your knifes for everything? Or do you have a professionaly made knife you use for skinning carving etc ?
Fox:
Thanks for all the great info guys... really helpfull :)
I’m thinking I’ll play around with the spring steel for a while but maybe will eventually buy some 1084
