eod, I really like the Pocket PowerPlier. I'm curious; what about the ParaTool do you prefer?
A couple things: 1. S31 has two full size blades - a 3" plain and 3" serrated vs a single 1/2 + 1/2 blade, #2. the lanyard ring larger on the S31, , #3. angled plier head capability on S31, #4. the wider nylon pouch vs the smaller leather pouch, #5. three more tools on the S31 - medium flat screwdriver, an awl, 2 blades vs one blade.
Of the five difference noted the main reason is the two blades vs 1 combo blade - that combo blade looks like a real pain to sharpen properly, secondary is the way Paratool opens and allows the plier to be operated at various degrees of angles (140 - 180 degrees) is a unique feature, not sure if I'll ever need it but it's there if I do. Shopping around on the WWW they both are about the same price.
