Testing a laser cut key versus a forged key

It's easy to overlook common tools like screwdrivers and wrenches. But not for [Torque Test Channel]. The channel is testing a lot of tools and in the video below they are testing a new key which is, oddly enough, laser cut instead of forged like the usual key.

You would expect a machined key to be weaker than a forged key. However, we were impressed with the big difference between the keys when you start taking measurements.

Speaking of measurements, we'd like to see more detail on the test setups shown in both the video and some of the included video clips. We enjoyed examining the internal grain structure of both keys.

Be warned. Watching this video will likely send you to the computer to buy new keys, especially if you don't have 30/60 headed keys.

The real question is why laser cut a key? It doesn't look like it's actually better than the forged variant. It is more expensive, but the installation costs for forging are higher. Particularly for a tool made in the United States, forging is both expensive and time-consuming on the limited number of large-scale forges that remain in the country.

As the video shows, the tool is perfect for its intended use. However, we still love these in-depth reviews of just about anything. For example, high throughput 3D printing. If you like common hand tools, what about screwdrivers?
