1. Levigated oxide of tin (prepared putty powder) 1 oz.; powdered oxalic acid 1-4 oz.; powdered gum 20 grs.; make it into a stiff paste with water, and evenly and thinly spread it over the strop. With very little friction, this paste gives a fine edge to the razor, and its efficiency is still further increased by moistening it.
2. Emery reduced to an impalpable powder 2 parts; spermaceti ointment 1 part; mix together, and rub it over the strop.
3. Jewellers' rouge, blacklead, and suet, equal parts; mix.
