:
I bought some RSS (Raw Spring Steel)
from Tulsa Auto Spring a while back to make some knives from.
I got it in 1/8" & 3/16" and from 1" wide to 1 14" wide.
The man was very honest with me which I always appreciate and told me that the RSS could be any "spring steel." That as y'all know includes the 10XX carbon series as well as 5160 alloy.
One of the pieces I got is marked 1084 so I do know for sure what it is and it is perfect for the purpose it's going to be used for. The rest is unmarked and can be any grade of carbon steel and since kitchen knives are going to be made from it I doubt its critical as to the grade as the heat treatment will be the most important step.
The hardening process for any of these steels is similar enough that good results can be obtained by heating to critical and quenching in warm oil.
I guess what I am trying to say is that if you buy from a spring manufacturer you may not know what you're truely getting unless the steel is marked. And if you want a specfic steel like 5160 it may be better to buy it from a supplier that can and will guarantee the type.
If I were going to make a cleaver I would want 5160 specifically for that purpose.
The local oriental super market sells really nice cleavers really cheap so if I made a cleaver it would be just for fun.
