I really like the wrap on this grip here:
Box cutters, utility knives --
I went to the box cutter/utility in the Fire Dept. where sometimes the duty gets nasty and abusive. The Husky brand, sold at Home Depot for about $8 is a good design.
It cuts open boxes, bags, slices through packing tape, plastic packaging -- most of the utility stuff you need to cut into out on a fire dept. call. If this knife doesn't do the job, we have some serious cutting tools in the pumper. *LMAO*
The blade secure mechanism has been improved and is more positive than the previous "fold over lock down" design. Now the blade locks into the frame with a positive button. Nice thing about these knives is that the replaceable blade has two working ends. You can abuse one end, save the other end for fine work. when the blade dies in battle, they're cheap to replace.
We once needed a flat point screwdriver in the field. Snapped the tip off the blade and got to work. No problem. Nice to have the "abuse option" when the battery terminals need to be scraped, stripping wire, gouging crud off something. And if you should lose it in the midst of duty, you're out the price of a decent tip for a mid priced dinner.
