And yet, Stahlwille performed just terrible in independent testing compared to many other brands.
I saw that but I can't agree with the testing method of using soft connector bolts. The test was competently done I just don't agree that the results are meaningful.
Yeah, I agree. The first rule of testing is to make it as realistic as possible. I can't remember the last time I used an open end, much less torqued an open end to failure using a long cheater bar on a soft fastener. All good brands have more than enough capacity.
The second is to remove variables, such as cleaning the wrenches and test bolt to remove any oils that might affect the measurement. Or see in the second video above the guy has a chewed-up allen key in a vise, and he isn't too careful about where each test wrench is placed on the allen key. There is no consistency in data collection. Another key rule of testing is to test more than one sample, especially if you get results that seem weird (as in the first video).
I also see in the second video that some wrenches get chewed-up jaws or bent jaws that are ruined by the test. The guy is declaring them victorious but the wrenches are ruined.
Everyone's work is different. If my work included regularly putting 300 lb-ft into a rod coupler, I'd likely use two wrenches side-by-side (or weld two together to make a special tool) which would spread the load and avoid ruining the soft fastener. If my job was to work on rusted suspension components of dump trucks in a quarry and a truck's design required open-end wrenches, then I'd optimize my tools for that. I don't have those requirements, so my priorities are different when purchasing. As they say, YMMV.
