It is easy to not think much about common tools like screwdrivers and wrenches. But not for [Torque Test Channel]. The channel does a lot of testing of tools and in the video, below, they test a new wrench that is, oddly enough, laser cut instead of forged like the usual wrench.
You would expect a machined wrench to be weaker than a forged wrench. We were impressed, though, that there is so much difference between wrenches when you start making measurements.
Speaking of measurements, we would like to see more details of the test setups shown both in the video and in some of the video clips included. We did enjoy seeing the examination of the internal grain structure of both wrenches.
Be forewarned. Watching this video is likely going to send you to the computer to buy some new wrenches, especially if you don’t have 30/60 head wrenches.
The real question is why laser cut a wrench? It doesn’t seem like it is actually better than the forged variant. It is more expensive, but the setup costs for forging are higher. Particularly for a tool made in the United States, forging is both expensive and it is difficult to find time on the limited number of large-scale forges left in the country.
