Need a radius grinding wheel for serrated knife sharpening...

I had an idea recently... I currently use the 1/4" paper wheels that I re-profiled and gritted that I use to sharpen serrated knives. I use another 1/4 inch paper wheel that i re-profiled to buff off the burr with some compound, and trust me when i tell you that the serrations are SHARP.

BUT, I had an idea that I would like to get a more "heavy duty" wheel for this purpose so I don't have to re-grit it and mess with the glue and all. So i began looking around. I have 2 ideas... 1. i can get a 1/4" grinding wheel (alum oxide) and re-profile it with a dresser (such as this) or 2. i can get a diamond radius grinding wheel that is already profiled (much more expensive. like this). Any suggestions? what are your thoughts? I am still planning on using my 1/4" paper wheel to buff out the burr.
 
I know this isn't really answering your question but I have the standard 8" wheels that are an inch wide I think. I use the corner of the slotted wheels to sharpen serrations. I only have one serrated knife and don't let it get super dull but after I polish between the teeth it will tree top hair. I'm not sure I would want to use a wheel to work up a burr as I think I would change the profile over time. If I needed to sharpen really dull serrations I think I would use a diamond coated needle file or the corner of a Sharp maker rod.

Anyways, just thought I would throw my experience out there since no one had replied yet. Good luck.

my thoughts exactly, the DMT tapered files are great for that. on a power device the only way i can think that would keep the serrations pattern intact is having a wheel at the exact diam. of each type of serration and going one by one. sounds pretty slow, dangerous, and difficult to me.
 
I have a DMT tapered file... and while it would get you by in the field, it does not work that great. What I have found works well is like I stated above. The paper wheels. I am just wanting something more "durable" like in the links I posted. I have posted some pics of a serrated knife I did with the paper wheels... so I know they work well. Thanks for the input, any more input will be greatly appreciated. :)
