For this portion, I lowered the angle by 2 degrees per side to try and limit the amount of rounding that would occur. I used 1um Diamond on Cow Leather Strops. The first go round was just ten very light strokes per side:

I did another 50 strokes per side with the 1um strops, this time with more pressure and was a little surprised to see some rounding considering I was working a full two degrees lower per side:

The next phase will be to continue on through the strops at least as far as .25um on kangaroo and get a perfect edge (I hope.) From there, I'll probably do a descending progression so that we're looking at the grits from a clean slate and aren't seeing scratches left over from coarser stones.

That's funny. :cheer:

At some point, I'd like to see an edge stropped at a higher angle (4-5 degrees like in Verhoeven's sharpening study) after the stones or ceramics, to see what it looks like. One theory is that it doesn't actually round over the edge, because the way the leather contacts the edge changes. Maybe? :whistle:

Sure, I'll flatten the bevels back out and give it a go.

I did a quick job of re-flattening the bevels with the 800# and 1000# Diamond Stones and the the Micro-Fine Ceramics:

Then I widened the angle by 4 degrees per side and stropped it with the 1um Diamond and Leather Strops with 10 very light strokes per side:

So much for that theory. :sick: Looks pretty rounded.

Thanks!!
