I use the wrench part to hold nuts while I unscrew the bolts, and I pry with it every so often do things like lift wall plate that got painted over. For those roles, it is great. But I've also wedged it between two pieces of firewood that have frozen together and given it a kick- they now fit in the wood stove, and the pocketwrench didn't get bent, so I'd say it's pretty tough.
