Inspired by the work of master blacksmith, Peter Ross. Cast Ductile Iron, hot oil finish. Fits a 3/4" diameter hole in a benchtop from 1-1/2" to 4" thick (if your benchtop is thicker, you may need to relieve the bottom third of the hole to 1" diameter). Low profile, flexible enough to grip the work firmly, but easily loosened with a mallet or hammer.
