Brother I truly feel your pain. I use to work in a wetland area in the north part of our state and within 6 months I lost an original VG-10 Spyderhawk and a plain edged Merlin both in the same area. I still have heartaches over those 2 losses.
I'm finding more brainy ways of keeping my Spyders safer and more well attached so that doesn't happen anymore hopefully. And it really hurts when you've developed a sentimental attachment to it.
I recently had a very close call with my very beloved G-10, ATS-55 Harpy. I was helping a lady load up several sacks of potatoes for a ministry we were helping. The potatoe sacks were that fishnet type of nylon and one of the sacks caught the clip of my Harpy.
Fortunately I believe the good Lord told me what happened. I called the lady and sure enough when she unloaded them she found the knife attached to one of the potatoe sacks. When she brought the knife back to me I gave her a hug that lasted almost 5 minutes ( at least it seemed like that long :rolleyes
and treated her to lunch.
You've just got to be careful and I'm going to starting rigging up special pocket flaps to maybe safeguard this from happening again.
