I used your basic design here but instead of cutting
sheets of metal I used 8 4” flat L brackets (4 for each side) and that has been
working wonderfully.

That sounds like a great idea. Post some pictures when you get a chance.

Nice idea

I've often lamented that I am not equipped to weld. It's nice to see a no-weld version.

One might consider designing the claws to be obtuse rather than right angles. Also, leaving a small radius at the inside angle of the claw will diffuse the stress at that point.

I've tried prying apart pallets with ordinary pry bars. It's hard and frustrating work. This double claw design is surely a boon.

a radius on the inside angle would certainly reduce the possibility of tearing, but remember this is a hand tool and that is 1/4" steel. the handle will bend long before the claw would tear.

The only thing I would do is put a bar in the heel of the claws as a pivot point
