This Staedtler Lead Pointer Tub is a rotary sharpener for 2mm leads. It comes with a large tub to hold shavings and a pad to clean the leads after sharpening. It can sharpen leads on their own or whilst in a mechanical pencil and automatically stops when then pencil is sufficiently sharpened. It has two holes -one extremely fine point for drawing on the left and a standard point for writing on the right of the lid. Directions on use: Place the leadholder point with the preset level of lead protrusion in the pointer’s main hole and turn together with the lid in a clockwise direction until the resistance eases off. The lead is now sharpened. Any graphite dust on the lead can be removed by gently twisting the sharpened lead around in the cleaning device.
