That’s the first time I’ve ever seen a metal strike plate on a plane. When my dad and grandpa made them, they put a small bevel on the ends of the plane to prevent any possible chipping or denting. They adjusted them by tapping lightly at the very end of the plane with a regular hammer. If the wedge was stuck, which should not happen, a wooden mallet could be used.
That’s not to say that it’s a bad idea, just a different way to skin that old cat. 😁
