Thread: Edge Picture at 100X after Chosera 1K Stone

Look at the edge straight down. If you see a reflection as in the first photo, the bevel is not set. The second photo the bevel is partially set. Once the bevel is completely set it will not reflect any light, as in the last photo, the shiny dots are dust.

Looking at the edge from the side, you can see if you are honing to the edge, but not if the bevels are meeting, fully from heel to toe. You do want an even stria pattern from heel to toe and edge to back of the bevel.

With hollow ground razors if you use too much pressure you will lift the edge off the stone as the blade flexes.

Feel every sharp edge you can find with your thumb, eventually you will know what a sharp edge feels like. A TPT will not feel a chip though, visually looking at the edge, is the quickest, non-destructive, most complete test of a fully set bevel.

Here is a good video of the test

.

BTW, that is not bread-knifing, it is jointing, where you are just removing any ragged burr and straightening the edge slightly. Bread-knifing is grinding the edge straight on a low grit stone with pressure.
