This is my 12 year old 3/16" diamond parting tool handle, with the fourth Robert Sorby 3/16" diamond parting tool in it, bin through a few.
It is 1.5" X 13.5" Ash with an oil and bees wax finish.This is the original finish.
It may look a lot like a Sorby handle ,that's where the design comes from.
It may not be the fanciest or the prettiest, but each time I pick it up, it's like an old friend.
