I always have my guys use them, in part just to be in the habit, and in part because, even when they know their use is optional, they understand the concept of protecting the insulation even without them a little better.
As for my favorite method of stripping, I prefer splitting the spiral by bending it, or untwisting it to my desired length, and folding the spiral back tight with my fingers, and bending back and forth until it breaks.
This always leaves a rounded edge facing the conductors, and I only sometimes have to use a needle-nose to tuck the inner-end edge back inside the spiral. Maybe my fingers are stronger than the average bear's, but I have no problem doing it this way.

I always use them on MC too. Seems like a cheap insurance policy.

Agreed: cheap and quick. I slip them on and inside the spiral before peeling back and trimming the plastic liner, so the connector and liner work together to keep the bushing in place.infinity said:

Marc, thanks for the link.
Another question: has anyone come across a damaged MC installation that could arguably have been prevented with the use of anti-shorts?

Not me, but I have a theory.georgestolz said:
With the bulk of MC armor being aluminium, any fault that would have occurred would have blasted away the offending jag of aluminium armour. The person finds that the circuit is tripped, and summarily resets the breaker. All (seems) well for the remainder of the installation's life. Probably not such far fetched scenario at the voltages where MC is typically utilized.

Should roto-splits be banned, modified or a new quick, proper method/tool be developed?

Damaged installation
Damaged installation
I worked on a job right before Christmas where one of my not too bright co-workers did not use red heads. I got on the job and was responsible for making up the joints. He put all the MC in boxes without red heads. We turned it on and they tripped. We had to go to ever box and put in red heads. There were at least ten shorts. Needless to say the customers were not too happy.

Thanks Larry, I hadn't thought about treating it the same as AC in opening it. I always just rung with a serrated edge, wobbled it back and forth a couple of times to break it off, and wa-la, pull off six foot, feather the end if needed (with mini needle nose), and stick it in a box, or MCC.

Blueheels, thanks for the reply.
What type of connectors and stripping method were used in that case?

What's wrong with a rotosplit? They are the quickest method available. We use them all day long on hundreds of terminations without trouble. I'm not understanding this one at all. It's not rocket science to remove the jacket from MC cable.

Follow Marc's link and you will see the issue.
It's interesting as I have been told parts of CA require the use of Rotosplits and will fail those that use other methods.
I use whatever I have on hand, hack saw, Rotosplits, dikes etc.
