Price range: See on Amazon

What we liked

  • + Stainless steel is described as withstanding sanding longer than regular steel, useful when finishing rings.
  • + Expanding design with stepped sizes covers many ring styles, and a hex wrench to expand and contract it is included.
  • + Short length is described as staying true while spinning, and it fits a lathe or a 1/2 inch drill chuck.

Trade-offs

  • - Medium covers only ring sizes 7.5 to 10.5, so other sizes need the small or large version, sold separately.
  • - Needs a lathe or drill chuck, so it is not a hand-held mandrel and costs more than a basic sizing stick.
