I bought a 22 oz eastwing when I bought my house... we will see which lasts longer...
In all honesty your hammer probably will if you don't lose it.
Mine has been used very heavily since I bought it. I did concrete for two years, helped frame a couple houses, and then used it for a summer building fence. It wasn't just used to pound nails either. I've grossly violated the warning sticker that it came with. I've used it to beat, pry, pound, clobber, break, hack, chop, hold, and destroy things that no hammer was ever supposed to do and it's held up admirably. In fact I'd say it's merely "broken in" at this point.
Estwings (sorry for misspelling it earlier) are something that could probably be handed down to the next generation, even if HEAVILY used.
