I know what you're going through all too well. Just recently, I lost my large 21 unique "Calvary" Sebenza, again. I was extremely upset because this knife was going to be given to my oldst son(6). I looked everywhere and gave up. This is the same knife I lost about 3 Christmases ago. I had the knife clipped to my pants and I went to through away a huge bag of wrapping paper and similar trash from our family Christmas. I lifted the bag over my head, and into the trash can, the bag went bye bye. Well, it wasn't until later I realized that the knife wasn't in my pocket any longer. I went though the garbage can and I saw the knife. The knife's clip had snagged the bag as I threw it into the garbage can and never even felt it.
Anyway, this past Saturday, I took my oldest son to a local gun and knife show. As we were driving down the road, he says to me,"daddy, did you lose a knife?" My heart sank, andI said, "yes. Why?" He said becaus I see one wedge under the floor matt and door back here, I stopped and looked as he unbuckled to dislodge it, and there she was.
So, from one guy to another, I hope it turns up. That's the hardest pill to swallow for me when carrying an expensive tool like the Sebenza, the fear of losing it.
