ABSTRACT:
The present invention is a retractable scalpel device with two releasable latching elements. When the scalpel blade is in an extended position, each releasable latching element is accessible for depression by finger pressure to cause retraction of the extended blade. However, the releasable latching elements are located on opposite edges (top and bottom edges) of a cover housing and about halfway along its length. The releasable latching elements must be depressed at the same time for the extended scalpel blade to be retracted into the cover housing.
