There are several reasons, but the most important are that as the weakest point will be at the juncture of handle & guard (the tang will have support from the rigid handle material) it must be made as strong as possible, also when heat treating, any sharp internal angles will form a stress riser (essentially a starting point for minute cracks which may occur during the hardening process) consequently a radius at internal angles is desirable.

Hope I've explained that ok (& got it right):D


As to the amount/profile of the taper, I don't rightly know that one, althogh I'm sure someone will enlighten us

It sure does make it easier to slide the guard up the tang too.

Also, it takes that much more weight off the butt end. I'm like 'em light, fast, and well balanced. :D
