Used to crimp aluminum sleeve for wire rope. Succeeded to crimp the sleeve for 2 mm wire without difficulty by using the crimping part near the hand. There are many types flattened, but when wires are concerned about loose. In that respect this pliers can be crushed into a variant very useful. Because the wire-only crimping tool is expensive, it is stupid to purchase for several uses. I bought this pliers for testing but it was a great answer. It also has excellent performance as a pliers as well as sharpness of blades because it also allows easy insertion of force. It is something that is common in monotail but it looks a little different from the picture, the blue grip was deep bluish.
