My grail knife is a SHBM or that new BM that Jerry posted which is even thinner. I don't need anything thicker than .25 inches and event that is a bit thick. I think .20 is perfect for a large camp blade. It will allow for chopping, batoning and cutting. That would prevent the user from tiring as quickly. Maybe even add some CG technology near the spine of the blade to lighten it up a bit more. Definitely a satin finish as well.

We can dream can't we?
