Knife Sharpening / Re: Is there still a wire burr...

Last post by BPalv - December 25, 2025, 02:08:10 AM

Hi, how are you? I can't find it. I saw a link to a knife sharpness chart here on the forum. It looks like a test. How to check the sharpness of a knife when you don't have a device. I remember there being mention of cash register tape -?Bess and cigarette paper- ?Bess .....
Thanks.
Merry Christmas everyone!
Peaceful skies.

The chart you seek can be found in Vadim's book, "Knife Deburring".  Amazing and informative book.

Again, nice work!
I have been attempting to do more restoration.  Just getting started down that road but,  I aspire to get results like that.
Thanks for posting,

The knife is now almost done.
The blade surface was refined with 800 grit wet & dry and some WD40.
The new convex edge apex measures ~30 degrees inclusive and needs to have it's tiny burr removed later, after which the sheath will receive a few coats of warm Granger's wax.

Beautiful work!
I would also like to know how to restore a handle like that.
Thanks,
Al

Hi. Lovely work. Can you explain the process of restoring the handle? More specifically, the work done to all the washers? Thanks.

Separately polished the miniature guard a bit, then put the handle back together using glue between all the washers:











How the knife looks at the moment:

This is how the blade looks after regrinding by hand both sides with only 400 grit wet & dry SiC paper using WD40 oil as a lubricant on a semi-hard rubber backing.
Somewhere in the past the edge had already been sharpened convex, so in order to remove as little steel as necessary i just evened things out to a new edge of around 30 degrees inclusive.
It's not completely finished yet (there is still a bit of edge damage left under the letter T), but that can also be done after the handle is re-installed.

Handle disassembled.
Tools used: a modified Swiss Made PB flathead stubby no.5, a thin scalpel blade with a purposely overstropped apex (polished blunt), and the flathead screwdriver on my old Amefa army knife.
