The Knipex High Leverage Diagonal Cutter 200mm, model 74 02 200 SBA, is a compact heavy-duty cutting tool for electricians, mechanics, industrial users, and tradespeople who cut wire all day and need a cutter that does not fold under hard use. This is a diagonal cutter designed for cutting hard wire, soft wire, and piano wire with less hand effort. If you want a jobsite-ready hand tool that balances cutting power, durability, and carry size, this one earns its keep fast.

What makes this cutter matter is the leverage. Knipex designed the cutting edge angle and transmission ratio to improve cutting performance while reducing the force you need at the handles. In plain terms, you get more cutting power from your grip. That is the kind of thing you notice right away when you are trimming repeated wire runs, cutting spring wire, or working through harder materials that make ordinary diagonal cutters feel weak.

The cutting edges are precision ground and additionally induction hardened to approximately 64 HRC, which is a real durability number, not fluff. That hardness is what lets the tool handle all kinds of wire, including piano wire up to 2.5 mm. For pro users, that means the edges are built to stay sharp longer under continuous work instead of giving up early after a few tough cuts.

Knipex also built these cutters from chrome vanadium heavy-duty steel that is forged and multi-stage oil hardened. That combination is a big part of why these tools have such a strong reputation in service trucks, electrical bags, and industrial maintenance kits. The forged joint axle adds stability, and the overall construction is aimed at long service life when the tool sees real daily use instead of occasional weekend duty.

Size is another reason this model works so well. At 200 mm overall length and roughly 0.67 lb, it is easy to fit in a toolbox, pouch, or work bag without feeling like a compromise tool. A lot of compact cutters are easy to carry but give up cutting ability. This one is built to stay compact while still delivering the kind of force professional users expect.

The ergonomic handle design and multi-component grips help the tool sit securely in the hand, especially during repetitive cutting. That matters more than people think. A cutter can have strong jaws and still be miserable to use if the handle shape fights you. Here, the grip is made for control and reduced strain, which is why this model is a solid fit for assembly work and other repeated-use applications.

The Knipex High Leverage Diagonal Cutter 200mm is a strong choice for electrical work, automotive service, construction, plant maintenance, and general trade use where wire cutting is constant and reliability matters. If you are a serious DIYer, it is also the kind of hand tool you buy once and keep for years. If you only cut light wire once in a while, it may be more tool than you need. But if you want a compact cutter with real bite, this is exactly the point of this model.
