This is a versatile tool that I find useful. When they first hit the shelves I thought they were only a novelty item but I have found many uses where it is indispensable such as a chisel holder. The design of this tool allows you to lock on to a chisel for example in a 360 degree hold verses my standard chisel holders that have a 180 degree grip. This prevents the chisel from flying out if it loosens while striking. There are hundreds of other uses but this is by far my favorite. I have another original brand of this style wrench however it lacks the locking feature that I feel is a must. In fact it is my opinion that a tool like this is absolutely worthless without locking capability. I love tools that are made in the USA but don't want to talk down tools that are quality made just because they are made elsewhere. The grips are comfortable, the jaws are strong and made of hardened materials and the spring loaded handles operate smoothly. I own the 6' model and liked it so I purchased the 8" model to add to my tool arsenal. I recommend the tool & think it has a placed in every professionals tool chest.
This product is not the same as the real Loggerhead pro-gear Bionic wrench. The quality is ****, bought it for my dad after bragging about my pro-gear wrench. He gave it back and said he wasn't going to use any tool not made in America. I used it for a week and the grip starting peeling back. Buyer beware
