Abstract

A device for cutting the stems of plants, such as flowers and the like, at an angle so that the stems can be easily forced into a support base such as foam plastic material. The device has an outwardly opening blade holder affixed to a ring member. A mount means supports the cutting blade within the blade holder. A cutting edge on the blade is spaced inwardly of the terminal ends of said legs where it is unlikely to inadvertently be engaged and cut the thumb. A spur is attached to the ring at a location spaced from the blade holder. The spur extends from the ring and is adapted to be received against the ring finger when the ring is received about the forefinger. The device is attached to the forefinger of one hand and can be manipulated to cut plant stems at an angle. The mount means includes a blade receiving slot that is formed within each of the legs, and the blade is positioned within the slot with the cutting edge thereof extending from one to the other leg. The thickness of the slot is changed to removably capture the blade therein.

a cutting blade, mount means for supporting said blade within said blade holder;
a cutting edge on said blade is spaced inwardly of the terminal ends of said spaced legs;
the terminal ends of said spaced legs are adapted to be engaged by one's thumb;
and a spur attached to said ring member at a location spaced from said blade holder, said spur extends from said ring member and is adapted to be received against one's second finger when the ring member is received about one's forefinger;
whereby;
said device can be manipulated by the fingers of one's ones hand to cut plant stems at an angle when the ring member is placed about one's forefinger, said spur bears against one's second finger and thereby stabilizes the device while a plant stem to be severed is pressed between the cutting blade and one's thumb.
