Hey, everyone. Just wondering what you all think of those collar-lock type of knives like the Opinels. A lot of people seem to know something I don't- were these the first locking folders or something? Am looking into an Opinel folding saw, but don't know how well they work or hold up. Are there any stainless varieties? I heard on Junglecrafty's channel that they were, but it says that it's carbon steel on Amazon. Then there's descriptions (of varius things) that say "High Carbon Stainless Steel."
