Martin The keys for backplate will stay with me all the time of course.
ok, then it works for your goals, but it wouldn't work for my father, which is also good for me. 😉
youdontknowme It could be keyed to use different keys than the belt.
of course, but my father, if he wanted to do it, he would do it seriously and that means he would worry (sounds complicated, but it's all theoretical) about what i do in public toilets. 😉
thanks for the idea, it's very interesting but probably a bit too complicated for everyday use and if you don't know how to build something like that i doubt other manufacturers do.
