Cutting device for skin for obtaining small blood samples from human or animal tissue in an almost pain-free manner. A blade (
) is made to oscillate by an oscillator (
) and is lowered into the tissue and again retracted at a relatively slow speed. In a first embodiment, the blade oscillates essentially parallel to the cutting edge of the blade and the tissue surface. In a second embodiment, the blade oscillates essentially perpendicular to the tissue surface. An advantage of the device of the invention is the reduced pain during pricking.
