I don't know about the engineers but when I was "researching" they claim to be twice as thick as the other brands. Also said it could be used with a utility knife by those making signs or such. It also mentioned that it could be used for the sewing aspect. Google in the Alvin cutting mat. I found that Amazon was the cheapest with free shipping. I really like the mat! Look it up and you will see the description.
