Abstract: The present invention discloses a composite fishing line manufactured by entangling eight bundles of fibers selected from two different types of fibers, one being a high molecular-weight polyethylene fiber and the other being a high molecular-weight expanded polytetrafluoroethylene (ePTFE) fiber, such that the composite fishing line has the properties of both high molecular-weight polytetrafluoroethylene (PTFE) fibers and polyamide fibers to improve the strength, wear-resistance, cross-sectional roundness, and water resistance of the high-performance fishing line and achieve the effect of reducing the diameter of the fishing line.

Abstract: A cutting line for vegetation cutters or trimmers includes a line which has a pre-set length and is a solid line with a cross section. At least one first recess unit is integrally and continuously formed in the outer surface and along the axis of the line. At least one second recess unit is integrally and continuously formed in the outer surface and along the axis of the line. The at least one first and second recess units are arranged in a pattern. The recesses of the at least one first and second recess unit do not wear to each other when the line is scrolled and reduce the chance to injure the user's hand. The line is light in weight.

Abstract: A vegetation cutter includes a tubular casing and a power source is connected to a first end of the casing so as to drive a drive cable which extends through the casing. A cutting member is connected to the drive cable and located on a second end of the casing. A positioning tube is axially located in the casing and has an annular sleeve through which the drive cable extends. The sleeve has two rib portions tangentially connected thereto and the two rib portions are parallel to each other. Each rib portion has two ribs on two ends thereof and the two ribs contact an inner periphery of the casing. The ribs are flexible and position the positioning tube in the casing, and absorb vibration when in use.

A cutting member is connected to the drive cable and located on a second end of the casing. A positioning tube is axially located in the casing and has an annular sleeve through which the drive cable extends. The sleeve has two ribs tangentially and diametrically connected thereto. The two ribs are parallel to each other and extend in opposite directions. The ribs contact an inner periphery of the casing. The ribs are flexible and position the positioning tube in the casing, and absorb vibration when in use.
