This little knife is the evolutionary outgrowth of a series of knives and experiments which I have made. While sufficiently delicate not to interfere with the surgeon's view of the operative field, it is amply strong for the work for which it is intended.
The blade is perfectly round, 5 mm. in diameter, and extremely thin, 0.4 mm. in thickness. The face of the blade is flat and stands at an angle of 30° to the long axis of the handle. The shank of the handle extends in a half round stem down across the face of the blade to a point slightly beyond its center. This feature would at first seem to be of no consequence, but is, in reality, of the utmost importance.
It allows of a thinner blade; it permits the sharp cutting edge to be brought entirely up to the stem or shank, on either side
