These types of tools were used for scarification, venesection, lancing, and circumcision. 6Ī particularly well-preserved prehistoric blade mounted onto a handle was found in 1991, preserved in ice near the Austrian-Italian border (see Figure 1). Fracture and flake techniques were then employed to refine these early blades into cutting instruments with desired characteristics, making these objects among the first human-refined tools. 5īlades were initially composed of flint, jade, and obsidian, with specific pieces chosen for their sharp edges. 4 Excavations of archaeological sites dating to the Paleolithic and Neolithic periods revealed knives for surgical use as early as 10,000–8,000 BC. Kirkup, circumcision with sharpened stones, one of the earliest recorded elective procedures, evolved into knives used for basic procedures. John Kirkup, MB, BS-a retired surgeon and honorary curator of the Historical Instruments Collection at the Royal College of Surgeons of England-researched the history of surgical tools for more than 20 years. Thumbnails for newborn circumcisions, scarification via plant stems, and venesection with sharks’ teeth served as the first examples of sharp tools for procedures on the human body. Shells, razor-like leaves, bamboo shoots, and even fingernails may all be viewed as early surgical instruments. Pinpointing a specific period of time when a cutting implement became the first surgical knife depends largely on perspective. Tracing the history of this tool reflects the evolution of surgery as a culture and as a profession. The quintessential instrument of surgeons, the scalpel is the longstanding symbol of the discipline. Today’s advances in scalpel technology include additional safety measures and gemstone and polymer coatings. Later, surgeons prized speed and sharpness.

As surgery developed into a profession, knives dedicated to specific uses also evolved. While the word “scalpel” derives from the Latin word scallpellus, the physical instruments surgeons use today started out as flint and obsidian cutting implements during the Stone Age. The surgical knife, one of the earliest surgical instruments, has evolved over 10 millennia. For more information, please visit the ACS website.
