So I've been sorting my allen keys (Thursday night fun)
Can you tell which are metric (as preferred by us Europhiles) and which are imperial (as preferred in th US)?
I thought about using coloured tape or keeping the metric set on the metric shelf. Or just putting the imperial set in a the 'almost obsolete' cupboard
