You can't pay enough for a really good tool. This is one of those tools. I got this as a present from my wife. I guess she thought it would get her out of being that extra pair of hands. So far her plan is working.

I have used the Jawhorse for holding all kinds of stuff: Wood, doors, table top grinder, miter saw, bicycles, and welding projects.
The power of the jaws is substantial and for some projects may be excessive. The clamp is activated with a foot lever and the clamp pressure is controllable. The clamp has rubber pads on the metal to protect your project, but as stated before if you over tighten you can damage your project. This isn't a negative comment though because somethings need to be held in place and this clamp will accompish that.
The product is made of heavy gauge steel. This is not a toy or one of those tools that you pay for and wonder where the quality is.
The clamp sits on 3 legs that fold up. This allows for space saving storage. There is a plastic cylinder on one end that acts like a tire allowing you to roll the jawhorse over smoother surfaces (cement: not a brick patio) to where you want to work. This is good because it weighs 43.5 pounds. One of the legs can be folded around and used as a handle for carrying the jawhorse. It's not as easy to carry this way as the ads would have you believe, due to shape and weight, but this is not a problem. The weight really speaks towards to the strength of the construction.
I've really enjoyed using this tool for welding. It's allowed me to clamp projects at all kinds of angles making it much easier to get a comfortable position for welds. Careful though the rubber on the clamp will melt as rubber does when the metal touching it gets too hot.
