Additionally, the invention includes a gauge in combination with the scalpel for calibrating blade depth, the gauge consisting of a base, a slidable block with a tapered ridge and width markings and a slidable support for the scalpel, so that the scalpel can be abutted with the block for measurement and backed off for block adjustment.
