I have 2 CMT Ovolo bits I bought around 01 or 02 for a restoration project from the early 1820s or 30s. I don't know why they call them ovolo bits, I figured it was some fancy Italian word.
Outside of the profiles for ovolos and plunge round overs, to me are likened to the foxhound and English harrier they look pretty much the same but the harrier is a stockier dog, like the ovolo.
I recently bought a Whiteside 2058 for a project, my first instinct was to go to the CMT book but they didn't have the bit I wanted, (too short and stocky). The 2058 has a longer, narrower and more graceful taper to the tip.
Never bite the hand that looks dirty!
