Belt Sander - Edge Position Question

I just ordered a few ceramic and Trizact belts to try.
It'll give me a little bit more confidence in the equipment.

I may have already mentioned this... but I didn't realize that a high-level sharpness can be achieved with lower grits.
I just assumed a progression up into the 1000s was required. I've seen videos where knives straight off a 140 grit KME cut down a folded post-it note.

The Microtech video was a good one to watch for me. The guy took an unsharpened blade and in 4 total passes turned it into a scalpel. He used 120 grit, 600 grit, then a stropping type wheel.
 
Yes, the first time I made a hair shaving edge with a DMT Coarse (about 325 grit) I was shocked shocked shocked. I really learned something that day.

You might enjoy my toothy versus polished edge videos. There are only two. Here's the latest one:

 
Thank you. I’ll check out the videos.
I received the ceramic and Trizact belts…they definitely look and feel different than the SiC belts. I need to dull a knife so I can give them a try.
