What type of cut is NOT typically made with tinner snips?

Tinner snips, also known as aviation snips, are primarily designed for cutting sheet metal and can efficiently handle various types of cuts. While they are often used for straight cuts and curved cuts, their design makes them ideal for specific shapes and contours, as well as notches.

The reason for selecting irregular shapes as the answer lies in the nature of how tinner snips operate. They are optimized for straight and smooth cuts or distinctly curved paths due to their blades and pivot mechanism. However, when it comes to making irregular shapes, the snips can struggle. Irregular shapes often involve complex angles or jagged edges that require more control and precision than what tinner snips can provide.

This is why other tools, such as nibblers or even hand shears, would be more suitable for cutting irregular shapes in metal. They offer the precision and flexibility necessary to navigate the complexity of such designs, which goes beyond the capabilities of tinner snips.
