For punching five-pointed star blanks in matched sizes — components for pendants, charms, earrings and decorative metalwork where every star has to match the last. Set non-ferrous sheet — silver, copper or brass up to 18 gauge (1.02 mm) — in the die and strike the punch firmly with a mallet or hammer. The five punches cut stars of approximately 8x9, 11x12, 14x15, 17x18 and 20x21 mm.
The die block and punches are machined from tempered high-carbon tool steel for durable cutting edges, and the solid 76 x 76 mm (3 x 3 inch) block sits square under the strike. A cutting lubricant prolongs the life of the tool.

Common questions at the bench
What metal and thickness can it cut?
Only the non-ferrous sheet metal this product's description names, and no thicker than any gauge or thickness it gives. Do not cut steel or any other ferrous metal: sheet that is harder or thicker than the cutter is made for can chip or blunt the punches and the die.
How do I cut a clean blank?
Anneal (soften) the sheet and put a little cutting lubricant on the punch. Stand the die block on a solid, flat surface, set the sheet in it and seat the punch with its cutting end to the metal. Strike the top of the punch squarely and firmly, with the hammer or mallet this product's description suggests if it names one; one firm, square blow gives a cleaner edge than several light or glancing ones.
Will the blank need finishing?
Check each blank. Smooth any burr or sharp edge with a file or fine abrasive paper before the piece is worn or finished, and if a blank has bowed slightly in the cut, flatten it with a mallet on a bench block.
How should I look after it?
Use it only on the sheet it is made for. Wipe the punches and die block clean after use, oil them lightly and store them dry, with the cutting edges kept from knocking against other tools. If a punch sticks, tap it back out straight rather than levering or twisting it.
