Man, you guys and your tools! heh. But they are some nice tools
I do it the old fashion way, and it has yet to fail me with multiple lights, even ones that the bezel really stuck on there or thread-locked.
Just put the bezel on the sole of your shoe (running shoes work really well) and just twist. Depending on how tight the bezel is on there, might have to work it back & forth each way a little bit to break it loose. If it's really on there or thread-locked, dip the bezel & the top of the head into some hot/boiling water anywhere from 30 seconds to a minute, and then work the bezel again. If the head is all metal, you can use a heat gun lightly over it to loosen any thread-locker on it. Pretty simple to do, just need to be cautious of using a heat gun on anything.
This always works for me because some lights have different size bezels (like my L2P and my TM11.... way different in size), so the shoe method worked perfectly on both.
