Do they breed? Why do I have so many? And that's not all of them. There is one in the garage, and one upstairs where I am putting a bedframe together.

The wooden-handled ones are very, very old. My second and third hammers, bought on the cheap when I worked as a carpenter. But they are still going strong, although the framing hammer is a bit worn. Back then, nail gun tech wasn't nearly as sophisticated, so I drove a lot of 16D nails. Now I mostly use it to crack lobster claws on the occasional big hard-shell lobster, but its heft can come in handy.

I guess when the zombie apocalypse arrives I can use it for close work...
