It would have definitely worked then on S30V, I would say. 2 hours of sharpening? Ugh, I would have gone with diamond and made quicker work of it. I would then smooth it out some with a finer stone and finish by stropping.

After dulling my RSK MKI in S30V using it a bunch for a few days' worth of work:

1. I run it over the Smith's diamond pocket stone (alternating) 20-25 times, with minimum-medium pressure.

2. I strop it on leather (alternating) 50 times a side.

-- Takes about 5-10 minutes max. Then it shaves the hair off my arms just like it did when it came out of the box new.
