Knipex CoBolt Compact 200mm Bolt Cutter

The Knipex CoBolt Compact 200mm Bolt Cutter, model 71 31 200 SBA, is a compact bolt cutter built for cutting bolts, nails, rivets, and wire in a tool that is easy to carry and easy to control. This is a bolt cutter designed for fast, high-leverage cutting in tight spaces, overhead work, and service bags where a full-size cutter is more tool than you need.

What makes this one worth a look is how much cutting performance Knipex squeezes into a 200 mm body. According to the source data, it cuts soft wire up to 6 mm, medium hard wire up to 5.2 mm, hard wire up to 4 mm, and piano wire up to 3.6 mm. That gives it real range for electrical, mechanical, maintenance, and general fastening work. If you regularly run into stubborn nails, cotter pins, fencing wire, cable ties with reinforcement, or small bolts, this compact cutter covers a lot of ground.

The joint design is a big part of the story. Knipex calls out an efficient lever mechanism that multiplies hand force while keeping friction low. In practical terms, that means less wasted effort at the handles and more force where it matters at the cutting edges. The result is cleaner cutting with less strain, especially when you are working one-handed, above shoulder height, or in an awkward spot where body position is not ideal.

The cutting edges are precision ground and additionally induction hardened to approximately 64 HRC. That is important because this is not just about making the first cut feel sharp. Harder cutting edges hold up better against repeated use on hard wire and piano wire, which is exactly where cheaper compact cutters start to lose bite. The body is forged from chrome vanadium heavy-duty steel and multi-stage oil-hardened, which tells you this tool is built for actual work, not light-duty occasional use.

Knipex also adds a recessed section in the blade to make thicker material easier to cut. That is a smart feature for starting cuts on larger diameters and for dealing with anchor bolts or similar material where a standard straight edge can fight you. Below the joint, there is a gripping surface for pulling wires from 1 mm diameter. That adds a little versatility without turning the tool into a gimmick.

At about 0.72 lb, this compact cutter stays light enough for pouch carry, service calls, punch-list work, and ladders. The plastic-coated handles keep the profile slim and straightforward. There is no bulk here, which is the point. This tool is made for the user who wants strong cutting power in a format that actually gets carried instead of left in the truck.

This Knipex bolt cutter makes the most sense for electricians, maintenance techs, remodelers, metalworking users, and serious DIYers who want a compact cutting tool that still handles hard material. If your work involves frequent small-diameter cutting and you care more about leverage, edge life, and portability than oversized handles, this is the right kind of cutter to own.

Small enough to carry, strong enough to earn the spot

The Knipex CoBolt Compact 200mm Bolt Cutter is the kind of hand tool that makes sense the first time you use it in a place where a full-size cutter would be awkward or overkill.

• Who it's for: Pros and serious DIY users who cut wire, nails, rivets, and small bolts regularly and want real leverage in a compact hand tool.
• Why it stands out: The hardened precision edges, efficient joint design, and blade recess give it more real-world capability than most compact cutters.
