I have an ABLON clone that came with a second-hand Watson 66 bulk loader.
I've tried it a couple of times ( on modern film right out of the box), but with scissors... which doesn't work so well....
The photos I've seen from the various Leica manuals and booklets show the user employing a small knife to trim the film, holding the film, cassette and ABLON in the left hand, and with the right hand, drawing the knife along the curved edge of the ABLON, blade perpendicular to the ABLON.
I'll bet Leica made a special little knife for this, but I would probably use the little 2-inch pen knife that I carry all the time
I put the ABLON away , continue to use the small curved cuticle scissors that I carry in my kit bag.
If I were loading FILCAs or other cassettes (in the dark), I think I would definitely use the ABLON.
