Abstract: The invention relates to multi-use thin-walled tubular devices having a longitudinal slit with non-cutting overlapping edges and corners curved in a manner to provide scissor-like entry-ways at either open end and methods of making and using such devices. The device is rigid lengthwise yet flexible in circumference and has renitent qualities such that the overlapping edges are spring-like. All surfaces and edges are smooth so that the devices are user-friendly and comfortable when used as handle grips for holding and carrying built-in handles of certain carrying objects, attachable handles for carrying items without built-in handles, hand-held exercisers, physical hand rehabilitation devices, hand-manipulated fasteners, and hand-manipulated separators. The dimensions of the device, the material used, and the method of construction may be adapted for the specific application. The preferred method of making is injection molding and requires a specially-designed mold form.
