I am going to start out with the best description I can give with all the details I can muster from memory. The knife in question was given to me about 8 years ago and I haven't seen it for about 4 of those. So I do not have a perfect picture or any idea about special marking that you may inquire about. The knife was a folding knif, all silver in color(no others) but not polished it looked almost brushed. The handle was slotted not solid and made of two pieces screwed together not a solid handle with a slot. The knife was all metal no rubber, no grips. It had a belt clip to match the handle. The blade was the interesting part. It was almost a hawkbill style but instead of a gentle curve like most modern ones it was more like the older hawkbill/gardener knife, straight to about half the blade and from about the halfway point to the tip was curve. On this knife the straight part was serrated and the curve was not. The blade was not flat like a piece of steel with a sharpened edge. It was like the modern knives that have the very angular ridges an the thickness of the blade changes with those ridges. Lastly the word "Jaguar" and I believe a small symbol of one was on the base of the blade where it folded at. Also had a one sided interchangeable thumb screw. I will give example pictures of similar knives I have seen over the years if need be. Thank you for your assistance.
