The Park tool and the Wolf tool are different. Hard to compare the use of the inserts with the single use tool Park has.

Wolf is using 7075 Aluminum. It should be strong enough if it is built right. I would have left a little extra metal around the magnets, but I assume they've done some testing of the tools before bringing them to market.

Use it as intended as an emergency road tool (replace spokes, etc). Use the inserts with a 1" wrench at home if desired.

It isn't intended to be dropped off at the local bike co-op for thousands of non-mechanics to use it, and breaking loose stubborn freewheels by standing on it.

Aluminum tools? Mom has a pair of aluminum fishing sinker pliers. All aluminum except hinge pin. Deceptively cheap looking. Probably 50 years old by now, and as far as I know, still working. They've gone on many camping trips. Used for a lot more than splitting lead balls.

I woudn't be surprised if one could get decades of home use out of that tool, and likely would eventually dig it out of the pack, and start using it for daily use.
