Zogg, a WELL FITTED kydes should carry inverted just fine. BUT IS NOT WISE! Just think, you're lost, cold, hungry, you've got a pile of woood limbs, fresh caught (by hand) fish and when you took that head over heels tumble 3 hours back your inverted carry knife came out! Go with something that carries NORMALLY and has a good strap (or 2) around the handle.
Just my 2 cents worth. Oh and Welcome to the greatest addiction you can have that isn't against the law!
