AN infernal sharpening question

>Dave,

From back in my brain trained as a ceramic engineer I remember that float glass is formed on the top of a bath of molten tin which can form a VERY thin layer of tin oxide, an abrasive, on one surface. Perhaps you happened to pick that surface and the tin oxide acted as a fine finishing abrasive grit and polished your plane blade edges.

Also, depending on the type of glass and it's ultimate use, many times other coatings are applied, often made with titanium, chromium, aluminum or other metallic oxides. These coatings can be on both sides of the sheet. Any of these oxide coatings would be abrasive and may have put on that finished edge.

Just my $0.02...

>all stropping does is bend the last, impossible to feel bits of a wire edge back and forth until they drop off. IF you strop at the very end with a strop with no abrasive, you get this result - if you strop with compound you remove more metal and the effect is different.

What you did was strop on what is basically a very unforgiving strop. - and it works. A plain hard leather strop will do the same thing - only be easier to use.

Back and Penny thing?

I envision placing a penny somethere along the back of a blade, sorta; along the lines of DC's ruler trick. Right?
