A member of our tying club came across a tool which we can't identify. I'm unable to send a pic or sketch so I hope my description will do. Basically it is like an aluminum wing burning tool except it has crossed tynes that will grip material upon releasing. The tips of the tynes are parallel along their length and about 3/8 inch wide across. Coming back from the tips of both tynes there is a slot for about 5/8 inch. Where these slots terminate there is a hole slightly larger than the slot width. What is the purpose of this tool? All thoughts are welcome.
