Gimmicky nail puller - GIF

[metric_taper]

The one I have has a built in slide hammer, was made in the 1950s.

I remember one as a kid from the 60s that our neighbor had. About 25 years ago, I was able to order the same design you're talking about.






I needed it to remove 1x8 pine ship lap sheathing that I salvaged from my garage made in the early 60s. Took most of a day to pull all the nails, but it saved damage to the wood had I used a pry bar. I notice now the handle say's "suregrip" but it has bitten me many times.
