The fuller, rounder of our two heart profiles, with near-square proportions: 12.08 × 12.27 mm, 14.6 × 14.83 mm, 17.57 × 17.85 mm and 21.44 × 21.57 mm. Blank them in matched pairs for earrings or graduated runs for pendants and charms — the punch gives you the symmetry that makes a heart read properly.
Block (76 mm square) and punches are hardened carbon tool steel. The set cuts silver, copper and other non-ferrous sheet up to 18 gauge (1.02 mm); strike the bevelled end with a suitable mallet and use cutting lubricant so the curved edges stay sharp through repeated work.
- Cutter block and punches are machined from high-carbon tool steel.
- Includes four wide heart punches: 12.1, 14.6, 17.6, and 21.5 mm (approx).
- Cuts non-ferrous sheet metal like silver and copper up to 18 gauge (1.02 mm).
- The solid steel cutter block measures 76 x 76 mm (3 x 3 inches).
- Each punch has a sharp cutting face and a beveled end for striking.

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.
