Brass Ring Sizer TSK

The weighted solid brass measurement mandrel with a polished hardwood handle, available in dedicated US and Hong Kong scale architectures. Determining a definitive ring size requires an unyielding, non-abrasive reference taper. The TSK Brass Ring Mandrel offers an exceptional blend of dimensional stability and precious metal surface protection. Machined from premium solid brass and paired with a contoured wooden grip, this instrument features deeply etched 360° sizing lines that allow rings to seat perfectly level for an instant, error-free readout.

Advantages

• Solid Brass Tool Metallurgy: Precision-machined from high-grade brass alloy to ensure a perfectly round taper that will never warp, bow, or bend over a lifetime of bench use.

• Custom-Proportioned Barrel Scaling: Unlike generic mandrels that squeeze multiple charts onto one tool, these sticks feature specific physical dimensions tailored to their exact scale requirements:

  • Hong Kong (HK) Scale Variant: Calibrated from Size 1 to 33 over a compact 165mm barrel length.

  • United States (US) Scale Variant: Calibrated from Size 0 to 13 over an extended 225mm barrel length.

• Contoured Hardwood Grip: Outfitted with an ergonomic 75mm x 30mm polished natural wood handle that ensures a slip-free grip and steady control during inventory sorting.

• 360° Circular Step Increments: Lathed with full-circle alignment grooves at every graduation mark, ensuring the ring shank sits square on the barrel for a definitive measurement.
