The preference for a number 15 blade for fine surgical work stems from its design, which features a smaller and more precise cutting edge than larger blades. This blade is specifically shaped to create delicate incisions, making it ideal for tasks that require high levels of accuracy and minimal tissue damage, such as in intricate surgical procedures or in sensitive areas of the body.

The number 15 blade has a relatively rounded tip, allowing for controlled and precise cuts, which is crucial when working in confined spaces or near critical structures. This capability makes it particularly useful in various surgical specialties, including ophthalmology, plastic surgery, and other areas requiring meticulous attention to detail.

In contrast, larger blades, such as the number 10, number 11, and number 20, are generally used for more extensive cuts and incisions in thicker tissues. While they serve important roles in different types of surgeries, they do not provide the same level of precision as the number 15 blade for tasks that require fine and delicate handling.
