shiny and smooth

My previous challenge is this series was about the colours of rust. This challenge is looking at the way metal can be polished and smoothed to create beautiful features, art, architecture or tools. This challenge is looking for subjects that highlight how metal can be shaped, polished and smoothed. The items must be shiny and smooth and highlight the metal so it must not be painted or covered in any form. Suggested items are cutlery macro shots, handles, handrails on stairs or items such as rings/ jewellery (not that close ups of gems break the rules).
