I used the TacTool quite a bit out in Idaho when we filmed Ron Hood's Vol 11 video. Loved it. Having the blunt end, with it's own separate blade, allowed us to do more potentially edge-harming things, and saving the main blade.
It was perfect for digging post holes, and digging up thistles.
The "gut hook" also functioned perfectly for lifting our trusty hobo coffee cans out of the fire without burning ourselves.
I arranged for some friends to receive RAT-7's in Iraq (contractors and soldiers). They've reported back ecstatically happy. Those knives don't quit.
Tha TAC knife is a huge favorite for the Marines. When I was down at Camp Lejuene a couple years back, they were all talking about them. The TAC was also the perfect size and shape to easily use to clear machine-gun jams.
