To match up

-Can you explain what is mean to "match up" with the manufactures grind?

-I guess they mean to match up the back part of serrated edge to front part.. of something..
because it's match-up and not only match. I'm not sure what is it here.

-I guess with "front" they mean to the front part of the serrated edge?
-Also the using of "put on" it's confusing. Is there other word to describe "put on" so I will manage to understand what is that?

A lot of people need to sharpen serrated edges, and we can do that on this (Sharpener). Most of time the backside of a serrated edge is flat, so what we do, is come up the backside with the honing belt to flatten the back of the serrated edge, to match up with the manufactures grind that's put on the front.
