A scalpel , or lancet , or bistoury , is a small and extremely sharp bladed instrument used for surgery , anatomical dissection , podiatry and various arts and crafts called a hobby knife.
Scalpels may be single-use disposable or re-usable. Re-usable scalpels can have permanently attached blades that can be sharpened or, more commonly, removable single-use blades. Disposable scalpels usually have a plastic handle with an extensible blade like a utility knife and are used once, then the entire instrument is discarded.
Scalpel blades are usually individually packed in sterile pouches but are also offered non-sterile. Double-edged scalpels are referred to as "lancets". Scalpel blades are usually made of hardened and tempered steel , stainless steel , or high carbon steel ; in addition, titanium , ceramic , diamond and even obsidian knives are not uncommon. For example, when performing surgery under MRI guidance, steel blades are unusable the blades would be drawn to the magnets, or may cause image artifacts.
Historically, the preferred material for surgical scalpels was silver. Scalpel blades are also offered by some manufacturers with a zirconium nitride—coated edge to improve sharpness and edge retention.
Others manufacture blades that are polymer-coated to enhance lubricity during a cut. Alternatives to scalpels in surgical applications include electrocautery and lasers. Surgical scalpels consist of two parts, a blade and a handle. The handles are often reusable, with the blades being replaceable. In medical applications, each blade is only used once sometimes just for a single, small cut. The handle is also known as a "B.
Morgan Parker patented the 2-piece scalpel design in and Bard-Parker developed a method of cold sterilization that would not dull the blades, as did the heat-based method that was previously used. The handle of medical scalpels come in two basic types. The first is a flat handle used in the 3 and 4 handles.
The 7 handle is more like a long writing pen, rounded at the front and flat at the back. A 4 handle is larger than a 3. Blades are manufactured with a corresponding fitment size so that they fit on only one size handle. The following table of blades is incomplete and some blades listed may work with handles not specified here.
Also called the "dinner knife" grip. The handle is held with the second through fourth fingers and secured along the base of the thumb, with the index finger extended along the top rear of the blade and the thumb along the side of the handle. This grip is best for initial incisions and larger cuts. Best used for more accurate cuts with smaller blades e. The scalpel is held with the tips of the first and second fingers and the tip of the thumb with the handle resting on the fleshy base of the index finger and thumb.
Care should be taken not to allow the handle to rest too far along the index finger as this promotes an unstable grip and cramped fingers. Graphical and model-making scalpels tend to have round handles, with textured grips either knurled metal or soft plastic.
The blade is usually flat and straight, allowing it to be run easily against a straightedge to produce straight cuts. There are many kinds of graphic arts blades; the most common around the graphic design studio is the 11 blade which is very similar to a 11 surgical blade q.

In such models, the blade is usually protected in a cartridge. Such systems usually require a custom handle and the price of blades and cartridges is considerably more than for conventional surgical blades. There are various scalpel blade removers on the market that allows users to safely remove blades from the handle, instead of dangerously using fingers or forceps.
In the medical field, when taking into account activation rates, the combination of a single-handed scalpel blade remover with a passing tray or a neutral zone was as safe and up to five times safer than a safety scalpel.
