Bulb planter with twin grips
Abstract:
A bulb planter includes a pair of blade halves cooperating to form a tubular tool head and a molded plastic handle body forming a pair of handles. The blade halves are preferably metal and riveted to the handle body. The handle body forms a living hinge for selectively pivoting the blade halves upon movement of the handles. The blade halves pivot toward and away from each other between a soil plug cutting position and a soil plug releasing position upon movement of the handles. A resilient member biases the blade halves toward the soil plug cutting position. The resilient member is preferably an elastomer ring encircling the blade halves. The handles extend in opposed directions substantially perpendicular to a central longitudinal axis and are manually movable against the bias of the resilient member to move the blade halves to the soil plug release position.
