Carry a small bottle of this to use on my strop to keep my wood carving knives sharp. This is a great product and keeps my knives very sharp. Much cheaper to buy it this way than buying the over priced little 1 oz jars from wood carving supply shops. Will last a very long time.

Great

Turned the silver totally black

Works as expected

Makes a big bang

Thanks
