Thread: Leaded strops - Linen? Leather? Both?

Back to the IP. Metals when oxidized form very hard crystals. Those crystas we have named such things as "Rouge," "CBN," "CrOx," and many others. Lead Oxide was available as White lead for plumbers and Assorted whites for artists:

The Lead white is apparently the brightest available white pigment.

To lead a strop, one just rubs a lead object against it until a bit of grey shows. That grey color disappears after a short time leaving lead oxides on the strop. That may be done on leather and other strop media.
Snapping the strop will put fine lead particles into the air. Whether that will make a personal life shorter or not is up to the user.
YMMV
