Oh; I could forge a knife out of it, but who knows what kind of steel it is, but why would you want to ruin this treasure? I kick my self for not bringing home some of my finds from Viet Nam. You can always get a knife; but where are you going to find this again? Keep it brother; take the advice of an old man.
God is good always; always, God is good!
"If thou wilst a keen edge win
forge it thick and grind it thin"
