You mean the thing on the thumbrest next to the opening hole? It's still the same needle file, diamond coated. I think that one was done with a triangular crossection needle file. First make notches on one side of the blade, keeping the distance between them even. Then being very careful to keep the file straight and perpendicular to the spine of the blade start cutting towards the other side. I tried making notches on both sides, but it actually made it a little harder to keep the file straight. And when it's done try to make all the cuts the same depth/width.
I guess it could have been done with a Dremel tool with a cutting disc bit on it, but I just don't have the rock-solid control on those things, so I prefer to do it all just with needle files by hand. Diamond-coated files work best, plain steel wears down much too fast and takes too long to cut good steel.
