Scalpels

There are three varieties to choose from: traditional cutting blades with a monomolecular edge, laser scalpels that cauterize as they cut, and nanotech scalpels that separate tissues along cellular lines without damage. Each has different uses.
Laser scalpels help the surgeon because of bloodlessness, but can dazzle anyone unwary enough to look into the beam, even though the scalpel can only cut within its focal length.
Monomolecular blades require no power supply and quickly slice through most matter with minimal effort.
Finally, Nanotech scalpels cause minimal disruption of tissue but operate slowly.
There is current research in an experimental scalpel that utilizes Transporter technology.
