Or just use somebody with better blade control. Doug has horrible form for cutting, and despite his FMA background, I feel that he is very lacking in practical cutting experience. Hitting pigs sideways with blades, flopping blades, using them as axes not edges..... Can cut a 1" hemp rope but not a fish- that's operator error!!
Of course the cloth won't be cut if the side of the blade is contacting clothing....
Doug looks like a cool guy to hang out with and grab a beer, but IMO he is horrible on the show, and how the tests are performed seems to disrespect the edged tools produced. This episode and the claymore one show him attacking like a 5 year old would. If Jay was the one doing all of the testing, I'm sure the results would be much better. Love the show, hate when Doug gets on.
