I bought an Estwing 28oz hammer for driving door and stair wedges last year, the extra weight in the head makes short work of the job and some may call it total overkill but it's one of the better purchases I've made. I've then got a 16oz Stanley Antivibe hammer for battering chisels and tapping components together since it's got a wonderfully large and flattish face. Then I've got several wooden-handled hammers kicking around in various shapes and sizes, but my most prized is probably a little Stanley tack hammer similar to the Lie-Neilsen posted above, it belonged to my grandmother who was a seamstress who sadly passed before I was born, so it's just a nice little connection to someone I never got to meet.
I've been toying with the idea of making a similar-sized brass hammer for when I'm working on the machines and cutter blocks for when things need gentle persuasion to come loose or move slightly without damaging anything. I wouldn't pay £88 for one though! More like £5 in materials tops! :lol:
