It sounds like a well designed malleable cast tooth plate that could be riveted or welded on the underside of the jaws would have some demand.

Guys after trapping these nuisance beaver for a while now and traveling hours to a job, I can see why beaver trappers used teeth on their traps. I want EVERY advantage in my favor to catch the problem animal(s) and get DONE...stop the problem/damage. I say a trap like a #48 Newhouse...I like a closed jaw ( bigger jaw spread) might be the ultimate trap. Thoughts?

I like #14 jumps for beaver under ice. Due to not being able to adjust pan tension I don't use them open water anymore because of non-target catches. (Ducks)

Have you tried installing the Paws- I -Trip pans on them? They allow adjustable pan tension.

I have several big jumps with PIT pans. Really takes them to another level. I think I’m going to cut a little off one side of the pan so that the under spring doesn’t start lifting the foot up.
