The US Actually Funded Research For This Effect

Get your Henson AL13 razor here: http://hensonshaving.com/actionlab and use code "actionlab" to receive 100 free blades with the purchase of a razor. That's 3-4 years worth of shaves. Both items must be in the cart for the code to take effect.

The published paper on this effect from Berkely: https://digital.library.unt.edu/ark:/67531/metadc838482/m1/25/
