Shamrock blanks anchor a themed collection, make distinctive custom metal tags, and add decorative detail to model work. This set shears them in three graduated sizes from annealed non-ferrous sheet up to 18 gauge (1.02 mm): seat the sheet in the die block, drop in the matching punch and strike it squarely with a jeweller's hammer, working on a sturdy bench block or anvil.

Punches and die block are machined from hardened, tempered high-carbon tool steel, so the cutting edges shrug off repeated runs. Pair the set with a cutting lubricant and properly annealed metal, and each blank will shear out as clean as the first.

  • Cuts three distinct shamrock-shaped blanks from non-ferrous sheet metal up to 18 gauge (1.02mm).
  • Punches and die block are machined from hardened and tempered high-carbon tool steel.
  • Includes three punch sizes: 11.7x14.7 mm, 17.2x13.8 mm, and 19.6x15.7 mm (approx).
  • The solid steel die block measures approximately 64 x 89 mm (2.5 x 3.5 inches).
  • Designed for use with a jeweller's hammer on a sturdy bench block or anvil.

Common questions at the bench

What metal does this punch work on?
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.
