I know it’s cheating since this is a hand-tool discussion…but I use a WorkSharp 3000 and MkII sharpening guide. I reset all my bevels when I get a new tool, and usually label the blade with the angle. By using the gauge, I get the same repeatable result and it takes less time to get the blade sharp the next time. 

That said, I strop almost constantly.  IMO, it reduces the need to sharpen by more than half. That is, I get double the life out of the edge before I have to go back and sharpen. Stropping is a superpower as far as I’m concerned. 

Good topic!
