I am a woodcarver and I used this to hone my knives on a leather strop. My knives are now sharper than ever! Great product and lightening fast shipping!

Great

Great product, came with a professional COA saying its purity and quality as well

Makes a big bang

Not what I was expecting.. would of been nice if had more pics to know what it was exactly..

Works as expected

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.
