#11 blade is most commonly used for which function?

• A. Shaving thick skin
• B. Incising fascia
• C. Excision of lesions
• D. Puncturing abscesses

Answer: (D)

The key idea is that blade shape determines its best use. The #11 blade has a slender, pointed tip designed for precise puncture or stab incisions rather than broad cutting along a line. That pointed tip allows a quick, clean entry into tissue to create a small opening directly over an abscess, which is exactly what’s needed to initiate drainage with minimal surrounding tissue trauma. Other tasks—like shaving thick skin, incising fascia, or excising lesions—benefit from blades with different geometries: shaving requires a broader edge or razor, fascia incisions need a blade that creates a wider, smoother cut, and lesion excisions typically use blades that give more margin control. So the pointed, puncture-friendly design of the #11 blade makes it best suited for puncturing abscesses.
