Thread: Newbie Q: can't get razor sharp enough

As said it does appear the edge is not fully developed, the goal is to get the edge as chip free and straight as possible. Looking at the edge, straight down on the edge will show you where/if the bevels are not meeting.

Looking at a bevel from the side, will show you where you may not be honing to the edge, if deep 1k stria or previous grit stira has not been removed and may end in a chip at the edge or if you have chips or crumbling edges, but they will not show you if the bevels are meeting, fully. And if they are not meeting, you don’t have an edge.

A 12k super stone can finish an edge well and is a much more versatile stone than most use it for. But tends to load up easily, which for a finisher can be frustrating. A swarf loaded stone can undo what you are attempting to do with that stone, which is to perfect the edge.

It is simply a matter of removing the swarf from the stone face with a scotch brite pad, a rubbing stone, nagura or a diamond plate. When using a 12k super stone, I first remove the previous grit’s stria, then resurface the stone face a few quick laps with a diamond plate, then do finish laps on a clean stone. A 12k edge stropped on chrome oxide will give you a smoking shaving edge.

Take an edge pic as shown in the Second Try at Honing thread and you will see where the bevels are not meeting,(the shiny spots). I think you are very close, nice even stria on the bevel, just probably need a bit more to get them to meet, the 12k should easily do that.

Comparing to a feather edge is not helpful, as those edges are coated, and that is a completely different process. Compare to the edges and bevels in the recommended post.

Nice pics, which USB scope did you buy?
