As yet another reminder of how long ago I served "in a US Army now more memory than real", Leatherman no longer manufactures the PST II. The PST II is a proven classic, which also means its utility has been surpassed by newer models. I found it's not strong enough for heavy-duty work, but it's handy for light work. My Leatherman needs to be cleaned and oiled, and the tip of the small screwdriver broke off somewhere along the way.
Like knot skills, a Leatherman represents self-reliance. I've left mine in a utility drawer since I left the Army; it's going back on my belt when I go out, as a talisman if for no other use. Here are the PDF instructions for the Leatherman PST II and a review.
