What does DiamondCore make?

DiamondCore Tools makes specialist pottery tools, and the listings say they are made in the USA. The best-known product is the handheld extruder, a blade with an adjustable depth ski that pulls handle strips and foot rings straight from a block of clay.

Which DiamondCore Tools product lines are in our catalogue?

  • Handheld extruders: a 4-pack (R4 Concave, R204 Concave XL, R101 Concave XS, R8 Double Line) and the single R4 Concave, with stainless blades and wood handles.
  • Carving and trimming set 1: P1 V-tip carving tool, T1 trimming tool, FP1 1 mm U-tip and SP1 sponge.
  • Scoring tool: extendable, five 1 cm prongs, 3.1 in hardwood handle.
  • L1 sgraffito stylus: diamond needle and 1 mm diamond ball tips, foam pencil grip.

How does DiamondCore Tools compare with other brands?

Its extruders compete with clay guns from COMIART, CZWESTC and Griiyakii, which push coils through 14–20 dies and suit small work. For trimming and carving, compare with Xiem, Mudtools and Kemper. DiamondCore focuses on a few precise jobs rather than full kits.

Who should choose DiamondCore?

DiamondCore suits wheel throwers who make mugs and footed bowls and want faster, more even handles, and decorators who carve sgraffito through underglaze. Beginners can manage without these tools at first; they shine once you repeat the same handle or carving pattern many times.
