Master Artorius cut his using a rather simple method, I will let him comment here and explain it. If I'm not mistaken it was as simple as sawing through the polycarb blade and cutting the film with scissors, but he will confirm this.
Yep. Used a hacksaw. You have to careful about getting bits of the plastic inside the hilt around the film but even if it gets in there it's no big deal. It doesn't really get noticed.
