There's a shop in my town that sells knives. I decided to go in and see if, by some rare chance, he sold straight razors. Not only did he offer new Dovo's and Boker's, but he offers straight razor honing for $15. I asked him if he could show me the process he goes through to sharpen his razor, and here's what he said:

He first takes it to a grinding wheel. I can't remember what the wheel was made out of, but it was charcoal black and fairly porous. I think he said it's the same as a scotchbite pad?

He then takes the razor to the largest, oldest, coolest hanging leather strop I've ever seen. 100 strokes.

He then takes it to a large paddle strop, felt smoother than the hanging strop. (I think it was) another 100 strokes.

He then uses a smaller paddle strop that felt extremely fine and and smooth. Another 100 passes. Maybe it was 50 passes on those last two...can't remember. He said the whole process takes about 15 minutes.

I know absolutely nothing about honing (yet!) so I wanted to ask you gentlemen if this sounded like a viable way to sharpen a straight razor. Based on the amazing vintage gear (strops) he had in his workshop, I was pretty convinced, but I wanted a second opinion.
