I have the same bone handled "Old Timer" pocketknife my wife bought for me 7 years ago, I also have on my belt, this minute, a Chicago Cutlery folder that my best friend gave me for being best man at his wedding, eighteen years ago. That cocaine does a number on your memory, doesn't it?
I carry 3 tools on my belt on a daily basis. The first a Gerber M600 multi tool, a pair of #4 crimpers (for crimping #12 non electric dets to M700 safety fuse) and a maglite. In or about 1994 I was issued my Gerber M600 multi tool, I carried it up until I had to turn it in in 2002, within a month I had convinced my new employer to purchase us one for every member of the section. I use my M600, conservitively(sp) at least 10-12 times a day. The #4 crippers have been exchanged 4 times simce I started carring them on my belt in 1982. The only reason they were exchanged was because they no longer crimped blasting caps tightly. The maglite was a birthday gift from an old g/f in 1996, I have worn out 3 cases for it since then. If you loose your tools that often you are careless, nothing else. If you are that careless with simple hand tools, no doubt you will be that careless with your life if the balloon ever goes up.
