SOG AKA Swap Out Greatness!
I bought one of these (and the sheepfoot serrated blade) from HH when I got an SOG Pocket Power Plier as my original Leatherman (street-legal before 'improved' into illegality as the PSTII) went walkies. Knowing the 3-way file would be the most (ab)used item in the inventory apart from the pliers themselves and so it proved... but the original surprised me: at least three years (four? Five? I honestly can't rememebr) hard use before I ruined the original coarse/fine/saw blade. Fitting the replacement is fiddle but easy-peasy so long as you do it inside a poly-bag (and have a couple of £1 Maplins Torx mini drivers or SOG-compatible L wrenches). Very highly recommended as it couldn't be easier or more economical (not unless the tools were dirt cheap or the saw was made of miracle metal)!
