Sharp Edges扎手

What it is

Sharp edges, or hot spots, are places where a fidget digs into fingers or pockets. They come from unbroken edges, small chamfers or aggressive texture.

Why it matters

Edge comfort is one of the clearest signs of finishing quality. Chamfers and edge radius remove hot spots without softening the design too much.
