Pencil Lead Pointer Sanding Block With Dust Troughs
This desk-top lead pointer for drafting and sketching is 130 x 60 x 12 mm. It has a 27 x 90 mm bed recessed 0.8 mm deep that takes a strip of 25 mm sandpaper stuck down with double-sided tape. Two 12 mm deep troughs beside the bed catch the graphite dust so it stays off your drawings, and a 10 mm cradle at each end holds a pencil or lead holder up to 9 mm thick.
Hex Grip Pencil Stub Extender
This 100 mm hex-grip holder lets you keep using a wood pencil after it has been sharpened down to a short stub. The 8.6 mm × 45 mm socket takes standard pencils up to about 8.4 mm across the corners, and an M3 screw driven into the 2.6 mm self-tap hole in the side clamps the stub of whatever size. The 16 mm hex body sits in the hand like a full-length pencil and won't roll off the desk.
