This is part of a current job.
Goal: Get a wenger pliers on a Vic 91mm frame.
How I did it:
First though was to use an old scissor spring (without backtool). This is my standard spring for special jobs since it gives you enough flexibility for adding tools.

However the pliers itself was a bit thicker than the old scissor spring and there was too much work to be done (grinding etc.) So I decided to use a standard pliers spring instead

I marked with a textmarker the parts to be removed (just around the middle pin of the spring) and used an old broken scissor to get a distance-holder.

Here is the result

and here is a mockup of a final knife (which will be shown soon)
