Kite shapes that step up in close increments — 14.69 × 23.06 mm, 16.19 × 25.4 mm, 17.69 × 27.75 mm and 19.2 × 30.09 mm — close enough to build graduated pendant sets or stepped, layered designs. Each blank shears from the sheet in one brass-mallet strike, identical across the run.
Punches and the roughly 76 × 76 mm die block are hardened high-carbon tool steel. Anneal your copper, brass, silver or gold sheet first — softened metal cuts cleaner and is kinder to the edges — and if annealing is new to you, our pickle bath guide covers the clean-up afterwards. Keep sheet to 18 gauge (1.02 mm) and use cutting lubricant.
- Punches and die block machined from high-carbon tool steel for durability.
- Includes four kite-shaped punches: 14.7, 16.2, 17.7, and 19.2 mm widths.
- Cuts non-ferrous sheet metal up to 18 gauge (1.02 mm) thick.
- Solid steel die block measures approximately 76 x 76 mm (3 x 3 inches).
- Ideal for creating consistent, repeatable kite-shaped blanks for jewellery.

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.
