A piercing saw, also known as a jeweler's saw or jeweler's blade, is a type of saw commonly used in jewelry making on sheet metal. It is usually used on softer metals as the saw is delicate. [1] [2] Like a coping saw, a piercing saw holds the blade in tension in a metal frame. As the fine blades frequently break, the frame is adjustable for ...
A "matting" tool has a pattern cut into the tip, and is used (mainly in chasing) to create textured areas. A "hollow-faced" punch has a raised contour (circular, or with some other shape) with a hollowed-out middle, and is used to stamp that contour, usually on the front face.

That means punch will be to the bottom side of the tool and piercing punches to top side of the tool.
This allows for complex shapes to be formed in sheet metal up to 6 mm (0.25 in) thick using simple tools. [4] that is essentially a small punch and die that reciprocates quickly; around 300–900 times per minute. Punches are available in various shape and sizes; oblong and rectangular punches are common because they minimize waste and allow ...
