On the topic of the H.D. Smith's unique offset pliers. Many have remarked on the utility, for obstruction clearance and knuckle safety - followed almost immediately by expressions of curiousness about them not being duplicated or produced longer.
This won't be a huge revelation to anyone, but I was thinking about it when re-organizing my plier drawers recently - I suppose bent nose pliers, also kind of uncommon, were meant to serve the same or similar purpose.
I don't have any vintage regular combination slip-joints, like the Crescent 926s below, in bent nose form.
But I do have a thin nose (Wilde), and some Needless nose (Klein) and long reach needle nose (unmarked) that are all bent form, as well as those offset German-made dykes that
@LesserSon and I discussed at length on the Lugzsonian thread.
There are others on the thread.
Just sayin', I guess bending rather than offsetting was the evolution path.
