When I first got it almost 30 vears ago, the first thing daddy said is to tie a rope to it the second you use it.
The same still applies, a lanyard will be attached to it in order to go to the cleat.
This is the only one I've ever seen like it, may be good reason. It will be easy to lose it, this is probably why they weren't mass produced.
