Abstract: An integrated shaving mechanism (ISM) comprises a 28- x 50-mm perforated arbor of 40-mm cylindrical radius supporting a 50-?m 300-mg inverted-headfoil-like cutterfoil with a 25×40-mm cutting pattern, held slideably under an attached complementary-patterned headfoil. Arbor, cutterfoil, and headfoil provide a few-mm thick shaving mechanism coupled to a shaver body having a motor and eccentric drive shaft that in minor design variations scans the cutterfoil either ±1-mm in reciprocation (R-ISM) or 1-mm-R in circulation (C-ISM) at 0.16K-cpm. With its 10-cm2 area of 0.7-mm-spaced cutting edges capable of firm facial contact, it cuts short hairs at up to 10× the rate of conventional shavers for fast closest-cutting. Arbor-supported cutterfoils and headfoils can be fabricated as thin and lightweight monolayers and multilayers of hard materials and coatings by mechanical and non-mechanical processes. ISMs can be embodied in the size and shape of reciprocator and rotary shavers.
