Important: the lever can / may only be changed when the head is slightly open! Thanks to the practical butterfly lock, this is easily done in a few seconds, even while shaving, by simply turning the locking ring, flipping the lever and turning the lock back. The handle and the head base plate are made of robust and high-quality ABS plastic (heat-resistant up to 70 ° C) - the end of the handle and the mechanism (rotary knob, head wing and control rod) are made of metal (stainless steel and brass). Blade change: by turning the wings on the head open or close (so-called butterfly system, butterfly = butterfly) and a normal, double-edged blade (e.g. a FEATHER FH blade) can be inserted without parts of the razor falling off. The razor cannot be dismantled, simply open the mechanism and rinse out for cleaning. The lever, which can be folded (at least slightly) open, changes the blade gap and, as already described, offers two different aggressive / thorough levels, depending on requirements.
