Which type of blade is specifically designed to cut from the inside out, resembling a claw?

The bistoury blade is specifically designed to cut from the inside out, making it unique among other types of blades. This characteristic allows for precision in delicate surgical procedures where it's essential to access areas without disturbing the surrounding tissue. The claw-like design of the bistoury enhances this capability, allowing embalmers and surgeons to perform intricate cuts that require close control and finesse.

In contrast, surgical blades, scalpels, and utility blades serve different purposes and are designed for more straightforward cutting tasks. Surgical blades and scalpels typically excel in making incisions on the exterior of the body or in more pronounced surgical procedures where outward cutting is necessary. Utility blades, on the other hand, are generally used for various general cutting tasks rather than specialized internal surgical operations. This distinction underscores why the bistoury blade is the preferred choice in specific settings where internal cutting is required.
