Fantastic. Best tool I’ve had for kitchen plastic waste pipes. The curved jaws line up and grip perfectly. Have always bought Knipex as the are quality products.

Great product
Invaluable for holding onto chromed and plastic plumbing parts. The rubber jaws are soft enough to grip well without scratching but also tough enough to last for ages.

Excellent quality and superb usability in my line of work.
Excellent quality and superb usability in my line of work. Always wanted to have pliers for siphons, TRVS and many other applications where a normal grip is not suitable.

Not Fit For Purpose
By far and away the worst "tool" I have purchased. I know chrome needs special care, I'm a plumber and dealt with the same for decades. Thought I'd give these well branded "knipex" a try. In short THEY DO NOT WORK. They slip and slide and have no actual grip at all. Back to the usual method of standard grips and a thick padded cloth.

Great for big nuts!
These are great for doing or undoing the nut on waste fittings. I also find them really useful for turning my pipeslice in awkward areas, with damaging the slice too much

Can't count how many time I've tried to avoid scratching an item by lining the jaws of the pliers with duct tape or a towel or other usually ineffective strategies, make that "always" ineffective strategies. Either the item got scratched, or it didn't get snugged up. These pliers do the trick.

カメラを雲台にセットしたり、照明をダボで三脚に固定するのですがそれぞれネジを回すのですが、手締めではしっかり締まりきれず、ちょっとした力で回転してしまったりしていました。 回す部分が黒い円形のなみなみした形状のつまみネジになっていたり、T字型のネジ頭とか、案外締めきれないもんです。 今回購入したこのプライヤーは先端が柔らかい素材になっており、きつく挟み込んでもネジを傷めないので安心です。 そして口の開き具合を簡単に調節し固定できるので挟み込み回すために力を使えるので便利です。 そして何より、撮影機材の黒くかっこいい機材の中にあってもこのプライヤーは黒と赤がバランスがよくてかっこいい。 おすすめです。
