Okay, for fun, I decided to do a preliminary study of stroke numbers with the strops,using the 14um diamond pastes right after the 1600 ceramic stones. I did 10 strokes per side before taking each picture:

14um - 10 strokes

This is what we call fast and furious, Clay! :woohoo:

I just realized I made an error in my description of the blog post: the smoothing out of the scratches appeared after a 100 strokes, not 50. And with the 5 micron paste after the 1600 grit stones (a previous blog post) I could still see improvement after 250 strokes, likely due to the better lighting.

But your results will be much more conclusive: not only more pictures, but also a better picture quality and great lighting.

Onward with the studies :)

The next five images are very interesting; I went back to the 1600# ceramic and recreated the scratch pattern, then went to the 3.5um Diamond and Leather strops with the following sequence: 50 strokes/side> 100 strokes/side> 150 strokes/side> 200 strokes/side:

1600# Ceramics

3.5um - 50 strokes

3.5um - 100 strokes

More to come... :)

and onward:

3.5um - 150 strokes

3.5um200strokes.jpg

3.5um - 200

The 1600# ceramics took a little chunk out of the edge and it's easy to track through the pictures exactly how the strops are working on the surface and edge.

Time for curveballs! I wanted to test cutting performance and I wanted to add in the 5k and 10k Choseras to the mix, so I reestablished the 1600# scratch pattern from the ceramic stones:

1600Grit-3rdRound.jpg

1600# Ceramics

Then I used the 5k Choseras:

5k-100strokes.jpg

5k Choseras - 100 strokes
I wasn't quite hitting the edge, so I did another 100 strokes:

5k-200strokes.jpg

5k Choseras - 200 strokes

Next batch will be the 10k Choseras.
