I literally don't know a pro trim carpenter who does not own - and use daily- an Estwing 16-oz straight claw leather handle hammer. I am in mourning because I misplaced mine- which i purchased in 1980, and am therefore purchasing my second one.  There may be more innovative hammers out there (now),  but you won't find one any better balanced, or any more comfortable to use.  I loved mine (I'm hoping I find it) and I'm sure I'll love "#2" just as much.  The guy whining about the slippery handle...  yes that's true for the first month or two - but don't worry, it will soon break in if you use it - they get better and better with age.  PS - pretty much ALL Estwing stuff is really good - my other favorite is the one piece 5 lb hand sledge.  Forged from a single piece of steel - no handle to come loose. Estwing makes quality stuff.
