Surgical scalpel blades and handles are organized by standardized numerical fitment systems: No. 3 handles fit small blades (#10 to #15), while No. 4 handles fit large blades (#20 to #25). Using the wrong handle-blade combination prevents secure slot locking and risks sharps injury in the operating room.
This master reference guide breaks down handle-blade compatibility, cutting profile geometry, steel alloy selection, and micro-milled slot fitment standards for hospital procurement managers and medical distributors.

Buying the fitment above: every handle and blade number in this chart is manufactured at our Sialkot facility — see stainless steel No. 3, No. 4 and No. 3L scalpel handles with metric ruler scales and knurled grips, sterile scalpel blades (#10–#25) in foil and bulk packs, and the retractable single-use safety scalpel for sharps-protection programmes. Wholesale MOQ is 12 units per model, and matched handle + blade sets ship as a single line item. For the regulatory and packaging side of blade supply, read the companion scalpel blade sizes guide.
Individual Blade Profiles & Surgical Applications
- No. 10 Blade: The classic curved cutting edge ("belly"). Used for making primary skin incisions in abdominal and thoracic procedures.
- No. 11 Blade: A triangular, pointed blade with a straight cutting edge along the hypotenuse. Designed for stab incisions, incising abscesses, and arteriotomy punctures.
- No. 12 Blade: A crescent-shaped, hook-curved blade sharpened along the inside edge. Used in suture removal, tonsillectomy, and dental mucosa incisions.
- No. 15 Blade: A miniature version of the #10 blade. Ideal for delicate micro-incisions in cosmetic, pediatric, and dermatological surgery.
- No. 20–24 Blades: Larger variants of the #10 blade designed for heavy skin and thick muscle incisions in orthopedics and necropsy.
Scalpel Handle Engineering: The 0.01mm Slot Precision
A scalpel handle's performance depends entirely on its front attachment slot. If the slot is milled loosely, the sterile disposable blade will wobble during incision, compromising tactile feedback. If milled too tight, mounting the blade requires excessive force, creating needle-stick and sharps risks.
Sialcraft utilizes multi-axis CNC machining centers in Sialkot to carve scalpel handle slots within ±0.01mm micro-tolerances. Forged from solid AISI 410 stainless steel, our scalpel handles feature metric ruler scales and ergonomic knurled grips.
