The beauty of a straight is that it’s a precision instrument with a single cutting edge which lasts forever if taken well care off. Obviously this is such an old fashioned concept that we need to reinvent it… or at least, that seems to be part of the logic behind Mr Jamshid Ilanlou’s invention.
A straight razor has a handle portion and a disposable multi-blade assembly with at least two blades as the cutting edge on at least one of its sides. A molded guard portion at the bottom of the blade portion prevents the blades from cutting into the skin by keeping the cutting edge limited to the surface in common among the sharp edges of the blades and the bottom guard portion.
It could be that the rationale was to make straight shaving more accessible for new shavers, even if the existing shavettes do a nice job of that.
