Explanation

There are very many hand tools for woodworking. A vice must hold the item firmly and its clamping part must not be deformed. A hammer’s face must be flat, without dents or cracks, and its handle strong. Handles are made of hard, springy wood; handles of soft or brittle wood are forbidden. The handle surface must be smooth, free of cracks and splinters; an iron ring may be fitted on the end so it does not split. The weight and size of the tool must suit the pupil’s age. Working with a handleless or faulty tool is strictly forbidden. Saws must be properly tensioned and sharpened; plane bases must be flat and the blade correctly sharpened and tight in its body.

Worked examples
A hammer with a cracked handle must not be used; it is handed to the teacher.
A heavy axe made for adults does not suit a Grade 5 pupil; a tool suited to age and strength is taken.
Class activity

Tool inspection: the teacher shows 5 tools (or pictures). The group marks “fit / unfit” and gives the reason: cracked handle, crushed face, loose blade, a good saw. Pupils do not touch the tools.
