Support BladeForums! Paid memberships don't see ads! I figure that I can break out the Flitz or the Mother's at any time...and I have. But, I generally just lightly use steel wool (SOS pad) on the handful of my traditional carbon steel pocket knives that I consider to be my users. I don't really like the look when the blade appears all blotchy with stains, but rather smoothed out somewhat into a more uniform grayish, friendly tarnish...that (in my mind) protects it from actual red rust. Hey - I can change all the above at any time.
