Three dolphins, graduated: 26.60 × 14.40 mm, 20.57 × 11.13 mm and a small 11.33 × 6.13 mm — sized so a pendant and its matching earrings can share one motif. Because the blanks leave the die identical every time, matched necklace-and-earring sets and layered pieces line up without fuss.
Block and punches are tempered high-carbon tool steel, with the 76 × 76 mm block sitting solidly under the hammer. It handles silver, copper and gold up to 18 gauge (1.02 mm). Work on a firm, non-marring surface and keep the punch lubricated for a clean shear.
Cuts three distinct dolphin shapes from non-ferrous sheet metal.
Punch sizes (approx): 26.6 mm, 20.6 mm, and 11.3 mm lengths.
Cuts soft metals like silver, gold, and copper up to 18 gauge (1.02 mm).
Block and punches are crafted from tempered high-carbon tool steel.
Solid 76 x 76 mm (3 x 3 inch) steel block provides a stable cutting base.
Our steel letter, number, and design punches are heat-treated to strike non-ferrous metals: silver (sterling, fine), copper, brass, bronze, aluminium, gold. Striking hardened steel will damage the face. For pewter and very soft alloys, use light strikes.
What size impression do I need?
1–2 mm for ring shanks and small pieces (initials, hallmark-style); 3–4 mm for pendant backs and signed plaques; 5 mm+ for presentation pieces and stamped jewellery components. Bigger is not always better — a clean small mark reads better than a struggle with an oversized one.
What do I strike it with?
A 1–2 lb brass mallet on a polished steel bench block. Do not use a steel hammer — it will deform the punch over time. One firm strike beats two soft ones for a clean impression.
How do I keep the punch sharp?
Polished punches stay sharp for thousands of strikes if you are hitting cleanly on a flat block. If the face starts blurring impressions, polish lightly with 600-grit emery, then a buffing mop on a polishing motor. Replace before the face deforms further.
