Why is there a burr?

I'll answer that.

Because the grinding process with a coarse abrasive has shattered the 
crystal structure of the steel, allowing the burr to form.

Why do you use a coarse abrasive on the edge?

I'll answer that.

Because that is the only way you can grind past the wear bevel on the 
back face if you only work from the front face.

Why don't you hone off the wear bevel on the back face (and the front 
face, for that matter)?

I'll answer that.

Because you won't use a jig, or the jig you use won't let you hone the 
back face.

Why don't you make and use a jig that will let you hone off the front 
and back wear bevels?

I can't answer that.

My comic relief for those spending too much shop time flattening backs 
and grinding to produce burrs. Please don't be offended.
