I bought an engraver from the hardware store for about $15. I put my SSN number on items like stereo eqiupment, TVs, etc. That way if it is stolen and recovered or shows up in a pawn shop, then there is a traceable number. The cost of engraving is not much but it is nice to have the engraver around for about the same cost as the first engraving. <br><br>I also put a piece of reflective tape on all my equipment. It makes it easy to find if dropped. Just shine a flashlight around and out pops the reflective tape. I use orange both to make it easy to see and to identify it as mine. Of course someone can remove the tape. I buy my colored reflective tape from www. galls.com in 1 inch wide rolls. They have 8 colors in 4 widths and two lengths. <br><br>A buddy of mine also uses reflective tape on his equipment. He spends hugh amounts of time cutting out intricate patterns and applying to the equipment in artistic arrays. He uses a variety of colors and patterns. We have a friendly contest running about the use of reflective tape.<br><br>REI used to offer "engravnig" of knifes. It fact it was actually a mini router. They route out letters in the plastic handles of knifes and then filled by rubbing a crayon over the groove. The crayon filled the hole. You could choose the color of your choice as long as it was in their 64 crayola box. <br><br>I had my SAK knifes done this way. I usually don't lend equipment but in case in a point of weakness I lend my knife to a buddy, they will at least know who they borrowed it from.
