Some of my friends started using climbing hooks as a key rings – back in the ’90s.
The same object is now a key ring only. The usage changes the function of the same object.
Moreover, the object prevents future mis-use: you can read NOT FOR CLIMBING USE on one side of the hook. I’m sure it’s fore safety reason (materials are different, I reckon). Is this a good example of a misleading cultural affordance? And what happens when the object is used for other purposes (e.g. fixing a net to a pole, to create an improvised goal)?
On a similar note: what does the CHINA mark mean, if visually connected to the alert written on the hook?
