No thanks, I don't want to prevent hand injuries.
To figure out how cut resistant a material is, it needs to be tested against a blade. The tricky part is that North America and Europe have two different test methods. Both of those test methods were updated in 2016. The most notable change was increasing the levels of cut resistance to spread out the range of grams to cut.

This is the North American standard for measuring cut-resistant materials. It uses a Tomodynamometer Machine (TDM-100) and the test is based on the ASTM F2992-15 standard.
Feeling overwhelmed by all this information? Me too.
Basically, the goal of this test is to measure how much force is needed to cut through a fabric.
Here are the steps to the ANSI test:
“A TDM-100 cut resistance testing machine.”
When the cut levels were updated in February 2016, the TDM-100 became the recommended testing machine for cut-resistant materials.
But here’s the catch: For a product to be legally sold in the European Economic Area, it needs to have the CE certified marking (pictured below). And the only test machine accepted for CE certification? The Coup Test.
The steps for the Coup Test are:

It’s easy to see why the ANSI/ISEA 105-2016 is now considered the preferred cut test method:
The most important thing to remember is that these two tests are not equivalent. A glove that held up for 3059 grams to cut on the EN 388 scale, can’t be considered an ANSI Cut Level A6 (3000 to 3999 grams to cut).
So there you have it, the major differences between the two cut level tests. Want more information on cut test methods? Check out our infographic by clicking the button below!
