I just rip off a bunch of more or less 4" (10cm) pieces of masking tape, stick 'em lightly on the front edge of my work bench, and tape the film end to the spool. Forget trying to trim the spool end with the ABLON. In the dark you'll slice your fingers. I don't even bother using scissors. Hold the bulk roll in one hand, the film end in the other. stretch out my arms, and tear the film against my thumbnail. This will work with most films except for somehigh speed recording and scientific films, which are on a polyester (Estar Kodak calls it) base. While you're winding the film on a spool stand the bulk roll on edge in the can so it's easy to grab and will neither unwind nor roll off the table.
