Goodell Pratt No.5 1/2 (gear change selector)
A truly beautiful tool from Goodell Pratt.
Like most hybrid breast/hand drills this offering from Goodell Pratt is designed to handle any and all drilling tasks. Its large enough and firm enough to do the job of a small breast drill while being light and handleable enough to be used like a normal hand drill. It has a very smooth mechanism, however changing gear is a bit fiddly as it will only do so in certain virtually random crank positions.
Functionally there are better hybrid drills about, however this is by no means a bad drill and that elegant design is a pretty unique.
