Thread: Tested with Coticule Razor Honing, fine linen Strop.Toilet paper cutting test.+HHT.

An observation, without wanting to pass judgement on anything...

If you're not looking at something with a loupe or scope there's basically no better way to tell the state of a burr than by cutting paper, any paper. You have to get a feel for it, and I personally wouldn't do it with a razor (occasionally after bevel set), but once you do it's pretty much foolproof. And in fact thinner paper is even better for it than kitchen roll, because it's more about feel than whether something cuts it or not. But any paper will do, once you've calibrated and know how it should be.

How you cut it is also important; OP was using a pull stroke there on tightly bunched kitchen roll by the look of it. The razor would have cut it better if it had a burr/wire edge remaining I assure you. Or it would just have pulled it off.

But the same hypothetical razor (with a burr or wire edge) would drop cut paper less well than one without.

Also a very pedantic, semantic point - you're extremely unlikely to roll an edge by stropping like that. You'll round it and feck it up, but you wouldn't roll it.

I use thin, soft toilet paper.

Yes, it's toilet paper from Costco.

Straight razor at the beginning of the article, retested after normal Strop process, with fine hair.
(Strop the surface is naturally dirty without paste.)

After removing the burr, it will leave a vertex, creating a new smooth shaving edge, will not cut the toilet paper, reduce the damage to the skin, pass the edge test of your own habits, and shave smoothly.

So I tried the tp test with a stropped razor & I found that if my pressure was light enough I could not cut the paper. And then I thought, so what ? Why am I testing for a burr at this late stage ?

I think the red highlighted text is the reason you are meeting so much resistance here., not the tp test or the HHT test.

If you are honing a razor to a burr you are doing it wrong... broadly speaking.
Of course a burr can develop when bevel setting, repairing or restoring an edge with coarse grits but if you need to test for a burr after stropping you may be spending too much time on the stones, using too much pressure or doing multiple strokes on one side rather than alternating sides.

If you search the site you will find we do not recommend forming a burr for razor sharpening.

Here is one link with comments from some guys who are experienced with both razors & knives.
