i always get random stuff in my youtube recommended videos. here we have a lady endorsing american crew shave gel.. she claims it does not have the blade dullers that other products have.. virtually everything i use is all natural.. and i shave with traditional style soaps.. so i'm assuming she's talking about the "goo" we all love to hate.

but anyway.. what is she talking about? what is a blade duller and who adds them to what?
