These are not your standard combination wrenches. They literally put a twist in it. The working ends are offset from each other by 90 degrees, which makes for a great handle that reduces stress and increases leverage. Beyond its heft and balance, the design of this crescent wrench/box wrench ratchet is much more comfortable, especially for repetitive tasks. By twisting the axis, that non-working end now makes for a more natural handle that diffuses pressure into the palm and across the fingers. The shaft of the tool is also slightly longer than many combo wrenches (small increases in shaft length greatly increase torque, or conversely decrease force required to achieve required torque).
I’ve been using this wrench for three months in near daily use. As a solar installer I use my gear heavily in adverse conditions: bolting solar modules to rooftops. When other installers tipped me off to this brand, I did some investigating. They are the only tools I have ever seen endorsed by the Arthritis Foundation. I figured that if they are good for arthritis sufferers, it has to be good for me, too. I was right.
