Never tried the Klutch tools, but a local tool store carries GRIP brand (Grand Rapids Industrial Products) I own several of their 24 piece wrench sets, last ones were $24.99 each. Works out to a buck a wrench and a plastic roll to keep them organized. I have not managed to break, bend, or otherwise damage any of these wrenches. Have lost a few though. The plastic organizer is good for about 3 months. Of course 15/16ths isn't included in the set but is common enough on my junk that I need to have one.
