Keeping an edge: care that actually matters

Stainless steel resists corrosion. It is not immune to it, and most instruments that die early are not worn out — they are corroded at the pivot.

Dry it, every time

Water left in the joint is what kills scissors and nippers. After any contact with water, wipe the instrument and open and close it a few times on a dry cloth so the pivot sheds moisture. Then return it to its case.

Oil the joint twice a year

A single drop of clock or instrument oil at the pivot, worked in by opening and closing, keeps the action smooth and displaces water. Wipe the excess — oil left on the blade collects dust.

Sterilise properly, store dry

Quality instruments tolerate autoclaving and alcohol. What they do not tolerate is being put back damp into a closed case, which turns the case into a humid chamber. Let them dry in open air first.

The mistake

Using nail scissors on anything but nails — cutting tape, thread, plastic packaging. One pass through a stapled label rolls the fine edge and no amount of care brings it back. Keep a second, ordinary pair for everything else.

When the edge finally goes

After years of honest work the edge softens. A forged instrument can be reground and reset by a sharpener; a stamped one usually cannot. That is the part of the price you only see in year eight.
