Came across this item today at work and can't fathom out what it is.
It is 7" long. I have deduced that you put something round (like a metal bar) into the end, pull the brass ring to the end to tighten up the metal bar then put the attached file into the slot and file away for some reason. I have tried to google it but not had much sucess with terms like "bamboo collet" "wooden collet" etc etc. It is bamboo by the way.
Good luck
