Excellent tool!
Typical Klein Tools quality! Seamer feels good in the hand and has a locking mechanism that releases when you squeeze the handles. Jaws align nicely and have notches every 1/4″ for no-measurement use.

Exactly as advertised
Sturdy and precise. Just know the markers on the edges donât have divets to line up sheet metal perfectly, so you gotta eyeball it. Great product

I’m a metal worker
And I really use the hell out of these all day long while I’m bending feet now I’d recommend

Super nice
Super high quality. Good alternative to the overpriced malco version however the latch that holds them shut is basically useless if you have them in your tool pouch they will not stay shut. Awesome other than that.

Strong
I like them. They work well. I sometimes wish the clamp heads could be switched out with larger deeper ones. I would prefer the handles (1) lock like a vise grip (when desired), and (2) when closed, I wish they would present a smaller dimension when locked. (My belt-pouchs are already filled with hand tools.)(*Caution: I attached a lanyard to the rubber handle but the rubber handles are not securely fastened to metal tangs. The metal clamps slipped out of the handles & fell while I was very high up, on the scaffolding. Thankfully, no one was hurt & the clamps weren’t damaged beyond a few dings. *I was able to rivet each side of the rubber handles to the metal tong in order to prevent them from coming apart. Now I can confidently use them with lanyards.)

Iâm a sheet metal guy so I use these alot, the quality isnât bad they donât feel that strong however. Will get the job done. If you donât want to spend the money for Malco tools I would recommend these !
