I removed the finish from a spec plus marin combat knife, here is how i did it. A) sand paper and steel wool, B) paint remopver or gas, C) tons of elbow grease. Ok here is how to do it. Soak the blade with the paint remover or gas, let set for a bit the take sand paper to it. repeat over and over again. soak the blade then rub with the paper, start witha coarse piece then work done to fine sand paper then onto steel wool. Worked great for me. Geoff.
