Abstract (en)
[origin: WO8402104A1] A razor blade edge tip has a cross-sectional shape defined, over up to 40 mum from the extreme edge by the equation w = adn, in which w is the tip chord thickness in mum at a distance d from the extreme edge; a is factor of proportionality not greater than 0.8, and n is an exponent having a value in the range 0.65 to 0.75. This results in a tip shape which is relatively thick very close to the edge but whose overall cross-section is narrow, compared with known tip shapes.
