ticket punch
A handheld device used by station staff to punch holes in tickets at ticket gates. Now largely replaced by automated gates, so the word is mainly encountered in historical or nostalgic contexts.
In the past, station staff used a ticket punch to make holes in tickets.
Compound of 改札 (ticket inspection) and 鋏 (scissors, shears). The exact historical derivation is uncertain, but the word describes the scissor-like tool used for punching tickets.
