Finally, I started applying increasing pressure.

No matter how hard I tried, I could not get the edge to dig into the sandpaper. I can guarantee that you can polish a razor with edge first passes on the 3M CrO microabrasive sandpaper all day long with no knicks or similar problems.

I ordered from Lee Valley. Here's the link if interested...

Huh, I wonder if that would work for coarser grits as well. That could speed up initial roughing in before gettting into the DMT's.

It's a good thing you said "decimal in the right place", or you would have received a reply from me immediately asking you if you had the decimal in the right place. Oh! You got an email from me anyway.

What is AO?

Hehe. I used "AO" to refer to aluminum oxide. Is that not the standard abbreviation here?

Here is a good thread.

You can go edge leading with chrome ox on a hard wood bock, if you are carefull.

Damn, two threads on the subject. I need to work on my googlefu

In the other thread you mentioned that you didn't want to give out the secrets (did you ever figure out where you were going with that project?), but would you mind sharing what kind of problems you ran into?

How careful is 'careful' when edge leading into hard wood?

I had problems with crumbling, burning, bubbles, warping, molding and demolding. Those were the major issues. Randy has been working steady on the hones.

Not very carefull, just pay attention, you can even go edge leading on paper.

Attaching a picture from the website link I included earlier that shows the grits available. According to the description, all are on mylar sheets. You wondered whether the ledge first pass would work on coarser grits. If you are asking about the 3M products being sold on the site, I have no doubt that you could sharpen straight razors with edge first passes with no problem.

You're a better man that I if you can effectively work edge leading on .5 micron chrome ox 3M film. I found with water and even with oil the stiction even honing extra hollow blades makes for a chatter like stroke. Not smooth. I didn't care for that at all. YMMV.

I've tried films and it does work.
A lot of people use them actually.

As far as diving in - it can happen on any hone as well.

Give the epoxy hone a try! Just be sure you figure a way to demold it when it dries!

Could those silicone baking molds be used as a mold or does epoxy stick to it? However, warping might be problem.

If it sticks, maybe some breakaway system would work? Using plastic as a sort of liner?

Mylar works real well for a mold release, but i was thinking about just pooling it on glass or something and leaving it there. I still might try it sometime, but spazola's problems seem off putting.

Olivia, what kind of hones have you had a blade 'dive in' to? I've never heard of that, nor does it seem possible with the ones I've used.

Yeah, Mylar, baking paper, parchment, freezer paper...

Jimmy it can happen on soft synthetics like Kings or Naniwas or on a slate like the charnley forest.
Takes only a little of a wrong move.
