I found this on Bob Kramer’s website today. It sounds insanely difficult, but here’s how you earn the title of Master Blade Smith:

To earn this title from the American Bladesmith Society, one must undergo years of study and then pass a Master’s Test. The test required building a 10″ Bowie knife made of 300+ layers of steel. This one knife had to cut through a 1″ free hanging rope in one swing, chop through a two-by-four twice, shave a swatch of arm hair (after the two-by-four), and finally, bend the blade at a 90 degree angle without the blade breaking. If you succeed, then you submit five flawless knives (including a 15th century Quillion dagger, a very difficult knife to make) to a panel of judges.
