By definition, a multi-tool is “any one of a range of portable, versatile hand tools that combines several individual functions in a single unit,” but you knew that already because the name is pretty self explanatory. The Ti2 Para-Biner takes that so far past the standard definition that just calling it a multi-tool doesn’t really suffice. For starters, it’s a functional (non-climbing) carabiner. Keys, bottles, bags–whatever you need a carabiner for. That base is built upon with the addition of standard or metric wrench openings (five on the PB5 model, seven on the PB7 model), a combination screwdriver / pry bar / box cutter, bottle opener / cinch, a cleat and the Para-Pulley–the integrated carabiner pulley designed specifically for paracord. Oh yeah, and it also holds 1/4″ Hex Bit Drivers. Your entire tool box is jealous.
