Support BladeForums! Paid memberships don't see ads! Hi, I'm new. Think I finally found the right place to post this, ha ha. I have a Puma branded SAK. Looks like a black Tinker deluxe with a partially serrated clip point blade. The serrations are TINY. Not sure how to sharpen them. Ran it over a Block sharpener and prayed. You guys seem to be the only ones who have ever heard of Puma branded SAKs according to the almighty Google,ha ha.
