General product and regulatory information only, not medical advice. This page does not describe how to use a scalpel on a patient.
Overview: three constructions, one regulation
Scalpels are grouped by how they are built: a one-piece scalpel (blade and handle made as a single unit), a two-part scalpel (a scalpel handle that takes a separate scalpel blade), and a safety scalpel, such as a retractable model, that adds a guard against sharps injury. Blade shape (the #10, #11 or #15 numbers) is a separate question, covered in our surgical blade types guide and the scalpel blade sizes chart.
Under the FDA rule for manual surgical instruments for general use, 21 CFR 878.4800, the device list names “scalpel blade, scalpel handle, one-piece scalpel” as separate entries. The rule describes these instruments as nonpowered, hand-held devices, “either reusable or disposable,” and classifies them as Class I (general controls), exempt from premarket notification subject to the limitations in 21 CFR 878.9 (eCFR/Cornell LII, checked 2 November 2026). That is why listings for scalpels look so different from one another: the same regulation covers a bare blade, a bare handle and a complete one-piece instrument. For the basics, see what is a scalpel.
Types table
| Type | What it is | How the rules name it | Limits and cautions |
|---|---|---|---|
| One-piece scalpel | Blade and handle supplied as a single instrument. | “One-piece scalpel” is listed by name in 21 CFR 878.4800 (Class I, exempt from premarket notification). | The regulation allows reusable or disposable devices, so the listing, not the type name, tells you which one a given product is. A used one is a contaminated sharp under OSHA 29 CFR 1910.1030. |
| Two-part scalpel (handle plus separate blade) | A scalpel handle that holds a separate scalpel blade. | “Scalpel handle” and “scalpel blade” are listed as two separate devices in 21 CFR 878.4800. | Handle and blade are bought and documented as separate items. Which blade numbers fit which handle is covered in the sizes chart. A used blade is a contaminated sharp. |
| Safety scalpel (for example retractable) | A scalpel with a built-in feature intended to reduce sharps injury; in a retractable model the blade retracts into the handle (see our retractable scalpel guide). | OSHA lists “safer medical devices, such as sharps with engineered sharps injury protections” as examples of engineering controls in 29 CFR 1910.1030. | Employers with occupational exposure must document annually that they considered and implemented appropriate commercially available, effective safer devices. The standard does not name a particular scalpel design. |
How the setting changes the rules
The setting changes less than most buyers expect. The OSHA Bloodborne Pathogens standard applies to “all occupational exposure to blood or other potentially infectious materials,” and it names scalpels in its definition of contaminated sharps: “any contaminated object that can penetrate the skin including, but not limited to, needles, scalpels, broken glass” (29 CFR 1910.1030, checked 2 November 2026). The duties below therefore follow the employer’s exposure, not the product label.
| Setting | What the standard says that bears on scalpel type |
|---|---|
| Clinic | The exposure control plan must be reviewed and updated at least annually, and must document the annual consideration and implementation of safer medical devices. Employees responsible for direct patient care who are exposed to contaminated sharps are to be asked for input in identifying, evaluating and selecting them. |
| Hospital | Same standard and same duties. Reusable and disposable sharps are both covered: contaminated reusable sharps go into containers that are puncture resistant, labeled or color-coded, and leakproof on the sides and bottom. |
| Laboratory | Same standard where employees have occupational exposure to blood or other potentially infectious materials. Contaminated sharps are not to be bent, recapped or removed unless the employer can demonstrate that no alternative is feasible or that a specific medical or dental procedure requires it. |
| Home care | 29 CFR 1910.1030 is an employer standard. It does not address household use, so this page gives no household guidance. Follow the product’s instructions for use and your clinician’s directions. |
What to check on the label and in the supplier documents
These are record-keeping checks drawn from the regulation, not buying advice and not a ranking.
- Which device it is. Does the listing describe a scalpel blade, a scalpel handle or a one-piece scalpel? Those are separate entries in 21 CFR 878.4800.
- Reusable or disposable. The regulation covers both, so the product’s own documentation must say which it is.
- Sterile or non-sterile. This is a listing attribute, not a type. Our surgical blade types guide shows, from FDA GUDID records, that sterile and non-sterile blade entries both exist, which is how sterile scalpel blades are listed.
- Any sharps-injury protection feature. If the product is sold as a safety design, the manufacturer’s instructions for use should describe how the feature works.
- Manufacturer instructions for use. Reprocessing of a reusable handle, if any, is governed by those instructions.
Care and replacement
Under 29 CFR 1910.1030, contaminated sharps, scalpels included, are not to be bent, recapped or removed except in the narrow cases the standard allows, and shearing or breaking contaminated needles is prohibited. Sharps containers must be puncture resistant, labeled or color-coded and leakproof on the sides and bottom, and during use they must be easily accessible and located as close as feasible to where sharps are used. Our red sharps container guide explains the colors and lid codes. Replacement intervals for reusable handles are set by the manufacturer, not by the regulation.
FAQ
What are the main types of scalpel?
One-piece scalpels, two-part scalpels with a separate handle and blade, and safety scalpels with a built-in injury-protection feature. FDA names the scalpel blade, scalpel handle and one-piece scalpel as separate devices in 21 CFR 878.4800.
Are scalpel blades sterile?
Some are supplied sterile and some are not. Sterility is a listing attribute; see the surgical blade types guide, which cites GUDID records for both.
Is a scalpel a medical device the FDA regulates?
Yes. 21 CFR 878.4800 lists the scalpel blade, scalpel handle and one-piece scalpel as Class I devices exempt from premarket notification, subject to the limitations in 21 CFR 878.9.
Is a scalpel a sharps hazard under OSHA?
Yes. OSHA’s definition of contaminated sharps in 29 CFR 1910.1030 names scalpels.
How does the blade number relate to the type?
They are different questions. Type is about construction; the number is about blade shape. Compare two common shapes in 10 blade vs 15 blade.
