Interesting. I wouldn’t see any reason why a dead blow hammer type effect couldn’t be achieved. Might take some experimenting to make sure it wouldn’t blow apart on impact, might require a rubbery type material for the shell.
I would think yes, but it would probably take some experimenting. I have a 4# dead blow hammer and I’ve never cut one open, but there is movement to the BBs that fill it, not a lot but some. I believe the BBS are housed in a metal container inside the rubbery plastic of the hammer itself. On that note, I wonder if it might be possible to use the core of a small dead blow hammer to build one…
