I kind of like the look of the swedge and I do think there can be some value in a swedge
Knife Guy:
I can see the esthetic appeal of a swedge.
It might help penetration in a thrust, though I don’t see much use for a thrust in a bush knife. For combat, a katana thrusts well enough without one.
A sharpened false edge is supposed to be useful for some knife fighting styles—e.g. Bill Bagwell’s “deadly back stroke”. I have no personal knowledge about that use.
A swedge might help a smith give a final adjustment to a knife’s balance—like the ubiquitous cooking instruction “Season to taste.” A production knife shouldn’t require that fiddling. Get the pattern exactly right before you start reproducing them.
Beyond that I come up dry. What value do you have in mind?
