Watch Knife Cut Through Full Coke Can

Bob Kramer is a master bladesmith who sells knives for thousands of dollars (literally, his custom-made knives go for $10,000 or more). They're also really really sharp. So sharp that they can get through a completely full can of Coca Cola easily. 
He's been featured in the New Yorker previously. The demand is so high for his products that people enter a lifelong waiting list for a knife. Five people are taken off the list chronologically each month and five more are chosen at random. 
He stopped by the offices of PopSci to show off the power of one of his knives. Check out their article here, where you can watch him slice through the Coke can. For a previous demonstration, see below.

I made a damascus steel knife using the same techniques in 1986!! Almost nobody was making them commercially back then. Mr. Kramer's knives are amazing, I didn't realize that he's here in Washington State.
