Williams Patent Glass Hone

Came across this curiosity on the interwebs. Reminds me (concept wise) of the little cupped glass hones for DE blades except this one you rub a slate "pencil" on the surface (which I assume came with the hone), I suppose to create an abrasive slurry. In a way it is also very similar, in theory, to the famed Bracketts Brazilian hone which was a hone made from melted down quartz pebbles and came with a coticule slurry stone to hone with. Anyone have any experience playing about with these kinds of things and whether they are effective in any way?

EDIT: Just to clarify the hone is the big slab at the top. The glass ball thingy is also a supposed razor honer but isn't the subject of the post, interesting nonetheless!

Now that is an interesting little gizmo. I have my Father In law's Lillicraps glass hone for DE blades but have never used it.

I actually use glass hones on my straight razors. I use diamond paste with honing oil to get the edge super clean.

I have one with a slate rubbing stone. You rub the slate on the frosted glass and hone. It works, but it dependent on the grit of the abrasive.

I too, tried it with CBN and Diamond paste with ok results. You can make your own “Glass Hone, by buying a glass tile, I use a 3X12 cost about $3-4.

Sand on 220 on a steel cookie sheet, to get the glass flat. Glass cuts easily. Once flat and with a frosted surface you can paste the frosted side or rub any stone on it to make a slurry.

Or better yet, use the frosted glass as a substrate for lapping film, holds film like crazy.

For paste there are much better surfaces than glass for pristine CBN and Diamond finishes.

The glass balls were to straighten the edge, more gimmick than an actual hone, more like a steel. Probably work better on a knife.
