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

I see you say leather and other stropping media, so is it best used on linen or leather? Is it best used as primary or secondary stropping? Or somewhere in between linen and leather? Thanks Geezer
