Here is a replica set of late-23rd century laser scalpels as used by Dr. Leonard McCoy in the 1960s series Star Trek. These were expertly machined out of aluminum by Gary Tierce (Nicksdad).

From Memory Alpha:
"The laser scalpel was a specialized medical instrument used for creating incisions in various tissues. It used a finely-tuned laser beam to make cuts. This device was available in different wavelengths for varied cutting strength and depth."
