Thread: Trying to gauge the right level of sharpness

As was mentioned a couple of good stropping sessions will tame a rough edge. If your finishing strokes are leaving a chippy edge then you need to address that issue TC

Here’s the brutal truth about a couple of edges. Surprisingly the worst looking edge was the better shaving razor which was finished on a Coticule under running water. The one with all the pronounced chips was the weeper edge...

Cool, what is the scale? I can see "50.0um" in the bottom-left but I don't see an accompanying length.

Oh, is it that flickering part just to the left?

I reposted it. There was some confusion as to who’s edge it was. In the reloaded video I made it much clearer that the photos were of my work and not his. I’ll post a link to the new video

I’m not sure about the length unfortunately. Thanks

My biggest challenge now is trying to reduce the margin of poor apex Integrity in the absence of proper magnification. Would joining the edge periodically throughout the progression followed by recovering the edge help safeguard against this?

You don't really need to joint the edge, just stay on your 1k till the larger chips are gone. You can easily see them with your 20x loupe by changing your viewing angles to catch the light or even by looking at the silhouette of the blade against a light source, not too bright of course for obvious reasons. I only use 8-10x & can always catch faults like that, & you can even see divots in the bevel that have not chipped when they catch the light.

As to apex integrity, the lighter your honing the better, yes, even at bevel set try reducing your pressure. I have seen a guy chip a honed edge by heavy stropping. The only reason he didn't roll the edge was due to how hard the steel was. Older razors which may have some rust compromised steel are prone to this.
