ABSTRACT:
Foliage trimmer with adjustable curvature of the flexible cutting blade assembly for the purpose of cutting convex shapes comprising of a trimmer body with pivotally mounted handle mechanism attached to a flexible curvature adjuster band with a uniform curvature maintainer mechanism attached to trimmer body to maintain equidistant spacing between the bolt axis and to prevent the formation of a ununiform curvature. The curvature of the flexible cutting blade assembly is adjusted with the release of the restraining mechanism with the fingers of the hand that also adjusts the pivotal movement of the front handle mechanism. The flexible cutting blades of the flexible cutting blade assembly are linearly reciprocated via resilient flexible cams of the drive mechanism connected to the motor means located in trimmer body.
