Spec Ops Tools Pry Bar, Crowbar for Demolition & Nail Pulling, High-Carbon Steel, 42" Demo Bar

Some good nail pullers have been posted already that are nifty for home use but honestly I think that for your situation with those large, whorled, deeply sunk nails and having a few hundred of them, none of these small tools are going to be acceptable. Look for a demolition nail puller or wrecking bar that has a 2' or even longer handle, otherwise you'll be struggling for the needed leverage IMO. Pricier but I think you'll appreciate it. You could also check out the 3' or 4' ordinary crowbars at the hardware store for one that has a nail-pulling cut, might be more affordable for being so simple and traditional. I like the 42" bar in the 3rd link... https://www.amazon.com/Gutster-60-Flooring-Demolition-Bar/dp/B06W56LTXD?th=1 https://ftaelectronics.com/24inch-gooseneck-wrecking-craw-bar-nail-puller-demolition-pry-chisel.html https://www.amazon.com/Spec-Ops-Crowbar-Demolition-High-Carbon/dp/B0GGTV37CX
