I have a lot of hammers, the vast vast majority of them I bought new.
I bought the vast majority of them before I had a good grasp of the secondary market.
I would have no problem, if I needed one, spending money on dead blow mallets or dead blow ball peens… I have a mix of Trusty Cook, Snap-on, and HF.
I do not feel this way, at all, anymore, about other hammers…I would not buy common tools at retail if I had it to do over. I went to two estate sales this week… both second day… and they both still had lots of ball peens and other common tools (SAE hardline, extensions, Channellocks, steel pipe wrenches, files, punches, chisels…). I would spend my budget on the tools that one cannot find used in good condition for cheap (metric tools, aluminum pipe wrenches, high tooth count ratchets, top of the line pliers…).
Point being… I would never have bought my ball peens used if I knew I would be seeing them for sale for $.50-$2 so damn often.
