Havana Retractable Cigar Punches

Are those Xikar punches retractable??? Or do you unscrew them yourself, punch your cigar, then screw them back together when your done? Looked on Yoube for a video of somebody with one but found nothing.

I figure what the hell. I'll just get a Xikar punch when I move. Might cost me more in Canadian currency and or + shipping, but I don't feel like cracking the caps of my sticks. As I've said I only buy cigars occasionally so the last thing I want obviously is to drop $10-20 on a good smoke only to mess it up with a cheap punch.
