Steel Used should read Steel Used/Heat Treat, which is at least as important. INFI steel, replicating the steel formula, isn’t really INFI without Jerry’s proprietary heat treat.
If heat treat is that important to you (which it should be) then you will choose steel and maker/brand rep. as two factors you consider important. To put HT as an option wouldn't make sense as I don't know what HT most of the knives I use have been put through...Examples - Spyderco, Benchmade, CRKT, Gerber - I have no idea of the heat treats they use for each of their different steels. <img src="/ubbthreads/images/graemlins/smile.gif" alt="" />
Thanks for the responses!
