/ Will we ever see revolution ice screws with a handle?
Will there ever be one with a winding handle... or has anyone tried the revolutions with the Petzl turbine handle?
I have my own homemade winding handle - a bit of fencing wire, a bit of plastic tubing and a bit of trial and error to get a universal shape that fits BD and DMM screws.
End result, a full hand winder (instead of finger and thumb). It's dead easy to put screws in - probably easier than a handled screw ( certainly less strain on pumped thumbs) but of course naff all use for taking them out as it's confgured one-way only.
Put it this way, when it comes to placing screws, I don't care much now whether it has it's own wee handle or not.
But, I wouldn't pay the ridiculous price Petzl want for a bit of wire, a blob of plastic and some string. I think mine cost £1 for some shock cord.

But of course it's not you taking them out, so it doesn't matter!
It could be that the DB handle is patented and so DMM can't do something too similar.
There used to be a ratchet for ice screws but I can't remember who made it now. The problem of course is that any mechanical device is prone to icing. I don't remember anyone having or using one.
I have some screws from the late 90s which were bought in the States - but I think were made by DMM - I think they were called DMM/Excalibur and at least at the time Excalibur were the US distributors for DMM. Anyway they have a hanger that if you push it in a little it sits fixed on the screw body, but if you pull it out it can spin freely. So it's sort of a very fiddly ratchet arrangement. Doesn't work that well really, I only use them now if I'm climbing with someone who has no screws and we need a 22 cm.
This is a wild looking screw, bloody expensive one too!
The right hand one of these three.
My mate was chatting to Rob Greenwood (DMM Rep) about seeing a picure of the revolution ice screws with a handle in an old DMM Product catalogue and wanted to know if and when they were coming out.
He was told the the handle which was very similar to the BD one was patented and DMM are having to redesign or scrap the handle idea.
Also Rob was testing the new axes at the moment.

I hope they figure something out soon!
