Proper term for this tool?

[gmartine]

Actually I'm a bit of a lazy arse, I'll grind an olive off with my little M12 rotary tool 9/10.

Ive got the Dickie Dyer olive cutter quick and easy cuts any size from 15mm upwards.

I used to use my hacksaw blade but an olive cutter/puller is now a standard toolbox item and well worth having.
Altho I still often try to 'hammer' them off with my adjustable spanner.

Same here. There are times you just cannot use a hacksaw and times you just cannot pull it. Nice to have the option though.

The 1969 Readers' Digest DIY Manual calls olives 'slip rings', by the way. Never used the term used outside of that book, but then perhaps it is an age thing?
