The Mattie drop spindle is part of the flywheel series with a 3" whorl. Hand turned from rosewood, it weighs 2.3 ounces.

The Central American species of rosewood in the whorl and shaft of this spindle is called cocobolo (Dalbergia retusa); it differs from other rosewoods in density, hardness, and in its vibrant color and grain patterning. Cocobolo is neither endangered nor a rain forest timber and it is being successfully plantation-grown to insure its renewability.
