Wondering if someone has info on 'snap on' pocket knives? I just bought one in a lot on eBay.I Don't have the photos yet but it is one that is probably easy to find photos of. It has black G10 handles with red snap-on logo, a semi-serrated blade with 7Cr17MoV on it and the words Service Model on the skeletonized glossy gray pocket clip with some numbers too small for me to read from the eBay photo. It would seem if there is more than one maker of these, this particular one is a higher end one. Can anyone attest to its maker, its quality, and what it may be worth in dollars in Excellent to mint condition? Any info you can give on this knife will be appreciated.
