The Channellock 337 is a 7-inch diagonal cutting plier — a side cutter sized for cutting wire, cables, and small fasteners in tight spaces where a full 8-inch cutter is too bulky. The cutting edges are machined for clean, accurate flush cuts on copper, steel, and small nails without the rough tail that mashed cuts leave behind.
It’s sized for electricians, automotive techs, and general-purpose repair work where one mid-length diagonal cutter covers most jobs. The ergonomic handle profile and balanced weight reduce hand fatigue over a long day, and the high carbon steel body holds its cutting edge longer than the softer alloys used on cheap import cutters.
Channellock has been forging pliers in Meadville, Pennsylvania since 1886 — the same small American factory, now five generations into the same family. The company is known for the blue-handled tongue-and-groove pliers that defined the category, and every tool in the core line is made in the USA from forged high-carbon American steel.
