The forming stick you reach for when a shank needs rounding, truing or easing up a size. Worked over wood rather than steel, gold and silver keep their surface — nothing to polish out afterwards — which suits repair work as much as forming new rings. The 9" length gives room for wide bands and larger men's sizes. If you're weighing wood against marked steel, our guide to choosing a ring mandrel covers the differences.

The taper runs smooth and continuous along the full working length, and the surface is finished so rings glide on and off without catching. One note: the surface is unmarked, so treat this as a shaping tool rather than a sizing gauge.

  • Extended 9-inch length provides ample working surface for wide-band and large-sized rings.
  • Solid wood construction prevents scratching or marking the surface of gold, silver, and other soft metals.
  • A continuous, smooth taper is ideal for forming, rounding, and enlarging ring shanks.
  • Features a smooth, finished surface to ensure rings glide on and off without catching.
  • Unmarked surface is designed purely for shaping and forming, not for measuring ring size.

Who it's for

A workshop essential for UK bench jewellers, silversmiths, and jewellery students. Its simple, robust design is suited for both repair work and creating new pieces from scratch, particularly where a non-marring surface is required.

Natalie O. ★★★★★

Finally got around to using it on a few silver bands that needed truing up, and the wood surface truly delivers — no scratches, no extra polishing step after. The 9" length gives plenty of leverage for gentle, controlled shaping, and it's sturdy enough that I don't worry about it flexing under press

Madison I. ★★★★★

The tapered shape makes it so much easier to ease a ring up half a size without marring the metal. I love that I don’t have to polish out scuffs afterward, which saves a lot of time on the bench.

Hannah M. ★★★★★

Finally switched from my steel one and the difference is night and day. The wooden surface is so much gentler on my gold bands, and the 9" taper gives me plenty of room to work up or down a size. Trueing a shank feels almost effortless now.
