I'm 66 years old and have been wrenching all my life, some of it professionally. I have Snap-On, Mac, Matco, Bonney, Craftsman, Wiha, and Harbor Freight. Knipex is German, and so is Wiha, but Wiha has an American division. In the 60's, Craftsman wrenches we're beautiful. Thin walled, tempered, as good as any Snap-On. Then they got cheaper and cheaper and came out with that thick walled **** they call a wrench( Allied ) just awful. They have improved somewhat with their latest stuff. The only line of tools that can match Snap-On in high polish(if you like to clean your tools), and thin wall for clearance, is Bonney. Bonney use to have the contract with the Air Force in the USA. I don't know if their still in business, probably not. Where superior tools shine is in tight clearance, and tight access situations. If you work as a pro, you will come across the need for the box end of the wrench to be thin and strong. Most people don't need professional tools, but when you need one, and you don't have it, a lot of time is wasted and time is money. There was a thread on here the other day about how to hold that oblong tip on a shock absorber on a class C. Waste hours fighting it, but Snap-On makes a nice little 3/8 socket made just for that oblong tip. Hours saved. For most stuff Harbor Freight will work, but for some stuff, only Snap-On has the tool. A mix of all of it has served me well over the years.
