I picked up this 'Meula Bison' knife yesterday at Scheels. Looking at similar knives on line, I came across a comment that stated:
"It is not uncommon for these knives with no hilt between blade & handle, to slip their sheathes even with a strap / snap,
and thus become lost."

I have a couple similar knives - One has a brass lined eyelet the other has no hole in handle - and I won't carry either
on my belt if I'm involved in much activity.
