I was thinking of trying to use some lapping film between my 1600 ceramic stones and 5 micron leather strops to remove stubborn minuscule marks left over from the various stones that the strops are not removing. Would the 9 micron diamond film be the proper grit to use for this purpose?
JCM, look at the Wicked Edge Grit Comparison Chart: got to the website, resources https://www.wickededgeusa.com/grits-comparison-chart-for-the-wicked-edge-sharpener/ That answers a lot of those type of questions, 1600 grit ceramics are much finer grit size than 9mcg lapping film. I think you’re results with the 1600 will improve if: 1) they break-in a little more (some seem to have a sintered coating that wears off) and 2) if you concentrate on your technique and use them longer, (ie more strokes). Hope this helps….That being said the lapping film does do a very good job removing scratches as you progress down through the finer grits films.
Thanks for the heads-up on the grit comparison chart, I hadn’t stumbled across that yet. Very informative!
As for number of strokes, I am doing 100+ for the ceramics and strops. Is that sufficient?
