Mainly Mathematical Instruments – ie: Bisecting Calipers, Protractors, and Golden Mean Calipers.
Everything here is individually hand-made. Kind of an artisanny type situation, so if you have any other ideas, I can possibly help make them real.
Bisecting Calipers
$65 – $85
These calipers are mainly used by people who need to quickly find center-points of non-flat objects. Particularly useful for luthiers and leather-workers.
Bisecting Calipers available here…
Golden Mean Calipers
$22 to $185
Golden Mean Calipers are available in various shapes and sizes. They are used for measuring artistic balance, and facial proportions.
All individually hand-made in 1.5mm thick stainless steel.
Golden Mean Calipers available here..
Protractors
$65 to $85
These protractors are designed to measure “inner” angles… particularly useful for measuring the angle between the nose and upper lip. A cosmetic surgeon asked me to make some about 15 years ago and I’ve been making them ever since.
The only place I have ever seen anything similar is police ballistics – measuring the angle which bullets enter walls. Put a pencil in the hole, and use these protractors to measure the angle.
