Hi - Personally I've only used it a few times to see what it was with both machines - I then found it faster and easy enough to just loop the paper into the clip and use my fingers to open the clips and clamp it in.
I do understand though there are people who may not have the dexterity for whatever reason and the tuf tool may help.
For both machines - I'd suggest contact the importers to see if they can get one for you & cost/timescale.
Jet - Tool France
Laguna - Axminster
If I had a spare one in my box of left over bits I'd have sent it to you, but sorry I don't.
Cheers, Nick
