A well-kept file belongs at the heart of a considered jeweller’s bench. Its teeth do the work of shaping metal; looking after them is part of looking after the finish.
What is pinning?
Pinning means small filings have become wedged between the teeth. Inspect the working surface regularly rather than waiting until it is visibly packed with debris.
Clear the teeth
A suitable file card or file-cleaning brush clears material from the grooves between the teeth. Choose the cleaner for the file you own: very fine, coated and specialist files may need a different approach. Follow the file manufacturer’s instructions rather than assuming one stiff brush suits every surface.
Store files separately
Protect the teeth when the tools are put away. A rack or drawer with wooden divisions keeps files separated; a cloth wrap offers protection when carrying one in a toolbox. Keep water and grease away from the working surface.
Check the handle
Before filing, check that the handle is secure. An exposed tang is sharp, and a loose handle should be dealt with before work continues.
A brush for the tool, not the jewel
Our file-cleaning brush for jewellers and silversmiths has fine, stiff metal bristles for removing filings from file teeth. It is supplied individually. Keep it for appropriate tool maintenance rather than brushing finished jewellery.
