Gedess Lead Pointer for Thick Leads up to 3.15mm - Swiss-made.

This is the legendary GEDESS lead pointer invented and patented by Georges Dessonnaz in 1941. It works so well on thick leads, that it has risen to a "must-have" status by those who use clutch pencils (variously know as lead holders, sketch pens, propelling pencils).

The Gedess sharpener accomodates the tip of your lead holder (up to about 8.6MM), from which you have ejected about 1/5" (for colored leads) - to 2/5" (for graphite leads) of lead. It will sharpen leads up to 3.15mm in diameter.

Here's the link to a schematic of the patented Gedess lead pointer.

Replacement sharpening rings are available.
