scalpel
It is not uncommon for surgeons to use other materials for their scalpel blades. Flint happens to be very brittle. It is actually fairly common to see obsidian blades in very precise delicate work. Obsidan blades being made from volcanic glass can be sharpened to blades finer than flint.
The scalpel handle holds a scalpel blade to facilitate use during Surgery. Some plastic handles with a blade already attached are disposable and intended for single procedure use on just one patient. Metal scalpel handles are sterilized in the autoclave for reuse in multiple Surgical cases. A fresh blade slots onto the scalpel handle and can be replaced as needed during Surgery by the Surgical Technologist or Scrub Nurse. Scalpel blades are intended for limited use to make sure that a sharp blade is always available for precision work. Different types and sizes of blade can be fitted to suite the Surgeons needs.
Laser eye surgery, no. Surgery using a laser instead of a scalpel, impossible to know, the only person/people who would know that is the surgeons.
