Paragraph 94. Somewhere in the shop there should be a definite place to keep the sharpening stone. A small table, or shelf on the wall, is very satisfactory for this purpose. The shelf or table should be at a convenient height and the stone should be either imbedded in the shelf top, or there should be small cleats so nailed as to form a receptacle for the stone to hold it reasonably solid when in use. The stone should not be carried about from bench to bench or place to place in the shop. The sharpening should all be done at the bench or table provided for that purpose. A can of suitable oil should be kept near the stone. A small try-square should hang at a convenient place so it can be readily used to test the blades which are being sharpened. A piece of leather to serve as a strop should be securely glued to a strip of wood and should form a part of the sharpening table equipment. The importance of tool sharpening makes it necessary that provisions be made to encourage students in undertaking the work. They will not be enthusiastic about sharpening their tools, unless suitable sharpening equipment is provided, and kept in good condition.
