TigerInTally is correct: Being struck in the forehead by the end with the two small projections is known as a "double tap."
i have seen wrenches like that that are used for the bottom bracket of a bicycle, but never those sort of protrusive things on the end of a hammer like device. it cant be for punching holes, that would be too imprecise. it must be for gently pushing or something. i thik you place it on something and tap the back with a mallet.
Nope. Hmmm, not exactly. But you are right in that the pins function is not directly related to its hammer function. Nope. Nope.
Nope. It is a hammer designed for a specific task. The other end helps accomplish the same task, but not by hammering.
Would that be a hammer used for some type of machine assembly. The pins might be used for belt tension adjustments? I'm thinking either by grabbing the belt with the pins, or by grabbing a small idler pulley and twisting against a fixed pivot point. More than likely for grabbing a small belt and pulling it tighter while adjusting the idler pulley tension mechanism.
