This make the little pulls-tabs for opening biscuits a waste of time.
A knife could be used, or scissors, but the things that make the pull-tab useless would make stabbing with blades dangerous as well.
This is my idea for a safe tool that will open a packet of biscuits, and catch any loose ones that fall out of the end.
It's a prototype, but I think it has promise.
Step 1: What you need.
A plant pot wider than your biscuits. Make sure you wash it first!
Something to cut the wire.
