It’s Mena. Knipex is a pliers specialist manufacturer founded in Germany in 1882. 140 years of focus on “gripping tools.” Rated as the world’s best in pliers, nippers, and long-nose pliers, it is a brand with a guaranteed spot in the toolbox of plumbers, electricians, and MEP workers. In this article I give a thorough spec-and-application breakdown of all 10 models: Cobra, Pliers Wrench, Nippers, insulated tools, and more.
メナWhen I first used a Knipex Cobra, I was amazed at how instantly the water pump adjustment locked in. “Can pliers really feel this different?” — that experience was what drew me into the tool obsession.
What Is Knipex? — A Pliers Specialist Founded in Germany in 1882
Knipex was founded in 1882 in Wuppertal, Germany. For over 140 years it has specialized in the manufacture of “gripping tools” (pliers, nippers, and long-nose pliers), and today supplies over 15 million tools annually to more than 100 countries worldwide.
In Japan, the brand has established its reputation as the “German tool that professionals choose” among plumbers, electricians, and MEP workers. The Cobra (water pump pliers) and the Pliers Wrench are tool categories that Knipex invented and popularized — their quality and usability have made them the standard for field tradespeople.
Top 10 Recommended Knipex Tools — Spec Breakdown of Models Chosen by Field Tradespeople
1. Knipex Cobra Water Pump Pliers 250 mm (8701250)

| Model | 8603180 |
| Length | 180 mm |
| Max Jaw Width | 40 mm |
| Jaw Profile | Parallel jaws (no teeth) |
| Features | No marring, pliers + adjustable wrench in one |
The Knipex 8603180 Pliers Wrench is designed around the concept of “replacing both pliers and an adjustable wrench with one tool.” Its key feature: no teeth (serrations) on the jaw.
