I'm of the "cut 'n patch" bunch more than the epoxy fill for this
purpose, meself...

But, I'll throw out yet another option I've used in similar situation --
cut back the area to get an adequate depth and place an 1/8 up to 3/16"
plate as the wear surface. If wanted, can use an angle for the corner.

It's pretty easy as don't need as precise a fit underneath as for the
inserted wood patch so the difficulty of achieving the perfectly flat
bottom and square ends is minimized and it's a permanent fix.

Disadvantage is it has to be painted and doesn't blend in as the wood
repair can be made to do if that's important.
