Knurled Band Sizer Tool with Long Body for Ring Expansion

This metal jewelry tool is designed for adjusting band fit by hand. It features a long cylindrical body with a stepped tapered expansion section, helping the band move through the tool in a controlled way. The band sizer function is supported by a visible marked working range of 16.5 mm to 24 mm. With its knurled grip and straight levered handle, it offers better hold and turning control. The tool is practical for small workshop tasks or domestic adjustments, especially when a band feels slightly tight and needs gradual enlargement. It measures 96 mm in length and 25 mm in base width, and is sold without packaging.
