Call me clueless, but why exactly won't BM resharpen serrations? Is it because of time? I understand they receive quite a large number of knives for life sharp daily. Is it more difficult or expensive? This is NOT a trash benchmade question, simply curious. I love my BMs and have 4 at the moment. I honestly just don't care much for serrations, only my auto stryker has them. So please enlighten me.

My guess is that it is a time issue. Part of that reason could possibly be that serrations can be subjected to heavier use, and they have been known to become damaged when used excessively, or on very tough materials.
If they get a knife in that has damaged serrations, especially the points, the customer might assume that it will be repaired to like new condition.

This is just a guess on my part though. I have only had one knife with serrations. It was my first Mini Grip... While I did use them occasionally, I prefer my knives to have a plain edge. It really isn't that hard to sharpen the serrations. I did mine with a small set of round and tapered files, and used a flat stone to lightly take the edge off of the back side of the serrations.
 
They might be more trouble than they are worth. With so many sharpening gadgets and widgets available these days, instructional articles, and videos on the web, it should not be a mystery on how to sharpen just about anything these days.
 
I don't know the answer re: Benchmades' why, but a few minutes with a diamond rat tail keeps my serrated blades sharp. The real trick is to knock the burr off on the opposite side.
 
If you have a sharpmaker, use the corners of the triangle rods in the serrations.
 
Another guess here- they don't want to be responsible for wearing the serrations down, they leave that to you.
 
I would say they don't resharpen the serrations because they do all their sharpening on a power belt sharpener... there's no way to use that with serrations. The serrations are put in with some kind of CNC machine.

The serrations might go on with a grinding wheel set up with the serrated pattern on the face. A quick "Bzzzz" and that does it. Matching an existing knife to that might not be as cost effective as there is a potential for mistakes to happen.

Yeah, that's what I was thinking. I've seen factory walk through videos and they do their safety hook cutters with a CNC robotic arm and grinder. I'm betting they use the same thing or something similar for the serrations.
 
Kind of odd actually because from what I have noticed most folks that like serrations can't get a straight edge sharp enough to cut…thus they like serrations. So they would be the last people to get serrations razor sharp. I would not have expected this.

My brother is one of those people actually. He likes serrated knives because he can't sharpen well and it gives a lot more time of use.

I use diamond tapered files and then a buffing wheel to deburr and polish. Wicked sharp.
