Razor strop paste, used in conjunction with a Strop, is an effective method of sharpening a "less than razor-sharp" straight razor. There are multiple pastes which perform differently, each intended for a specific purpose.
Yellow Paste has no sharpening qualities and is used as a leather strop conditioner on your "everyday use" strop.
The sharpening pastes should be used only on a strop reserved for that specific purpose and dedicated to that particular grit of paste.
