By the use of these cutters, hard or soft wood can be shaped with or across the grain on very small pieces without chipping the wood. The percentage of defective stock is re- duced to a minimum, and we can attempt to do some classes of work that could not he done by the ordinary straight cutter. The danger for the operator is greatly reduced, as the action of cutting is always smooth and uniform. The sketches herewith show the method l>\ which we can design and grind to constant shape cutters for this purpose. Fig. 1 shows a "top view" of the bottom collar as placed on the machine, with the two cutters placed on a slant, as desired to be oper ated. The dotted outside line shows the travel of the cutting edge and.

Fig. 2 represents the cutter laid out with corresponding points, to the position at which it stands slanting as operated, designed in such a way as to produce a perpendicular cut.
