The KLEIN TOOLS 1550-4 is a heavy-duty pocket knife built for trade professionals who work with wire, cable, and line materials in the field. It features an extra-large curved sheepfoot slitting blade measuring 2.625 inches, with an overall closed length of 4 inches. The blade is carbon steel and locks open for safe single-handed use during demanding cuts. The woodgrain plastic handle provides a secure grip in typical job site conditions. This knife is sized and designed for electricians, linemen, and utility workers who need reliable cutting performance in a compact carry format.
The 1550-4 is suited for heavy-duty line work, including slitting cable insulation, cutting cordage, and general utility cutting tasks on residential and commercial job sites. The curved sheepfoot blade profile concentrates cutting force along the belly of the blade, making it effective for controlled slicing strokes. It is a standard carry tool for electricians and linemen who require a dedicated slitting knife separate from their primary utility knife.
Designed as a general-purpose slitting pocket knife suited for electricians, linemen, and utility trade professionals requiring a dedicated sheepfoot blade for line and cable work.
No installation is required for this hand tool. Before use, inspect the blade lock mechanism to confirm it engages fully when the blade is opened. Follow all applicable job site safety protocols when working with cutting tools near energized conductors or pressurized lines. Store with the blade closed when not in use.
