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.

Customer Reviews (4.4 / 5 · 5 reviews)

Mia C. ★★★★★

The 21.44 mm punch cuts clean through 0.8 mm copper with barely any burr—perfect for matching earring blanks. I’ve already made four pairs this afternoon.

Alexander K. ★★★★★

I've been using the 17.57 mm punch to make earring blanks, and the square-ish heart shape looks really balanced. The steel cuts cleanly through copper sheet without any distortion.

Timothy ★★★★★

These punches cut through 0.8mm silver sheet without bending the edges even once, and the 21mm size is perfect for chunky pendants. The near-square proportion gives the hearts a nice modern look that I prefer to the skinny tapered ones.
