A trapezoid is a plane figure with 4 sides, only 2 of which are parallel.
When closed this box represents a trapezoid at each of its 3 sides. Each
compartment pivots off the brass rod running straight down the back corner of the box.
The compartments are able to turn freely around a 360 degree axis and will not tip
due to the weighted base (2 pounds of lead shot, 1 pound for the TR-5). The top
is a secret compartment which can be accessed from underneath.
The box comes
in a variety of woods, commonly birds eye maple, rosewood, and bubinga.
The finish is the most time consuming part of making the box and consists of 3 coats
of shellac followed by a top coat of paste wax with fine sanding and steel wool
between coats. No stains have been used on any of the woods.
The trapezoid is
available in 5 or 8 levels with all levels except the secret compartment
lined with black velvet.
