/diy/ - Do It Yourself

I bought it at a second hand shop. I paid 4 bucks for it. Rip claw and 20 oz with the blue rubber grip. it was a little rusty but that's it. they didnt know what they were selling. they had other shitty hammers from the dollar store that were also 4 bucks. I almost felt bad about it.

I just started a general labor job and bought a 20 oz Estwing. How can companies like Stiletto sell a 14 oz hammer and claim that it "swings like a 28 oz?" or something to this effect. Force = mass x acceleration? Is there any truth to these claims? Is Stiletto a meme?
