DMM Revolution Ice ScrewFrom £32, added Jan/2008, see all DMM news & reviews
announcement by DMM
It's not easy to build a good screw; you need very good steel for the tube, the outside teeth need to be precision ground so that they both pull in the tube efficiently and hold it firmly when under load, the tube needs to be heat treated so that it offers a perfect balance of hardness and ductility and the inside of the tube needs to be honed to a mirror finish to minimise any frictional resistance when it is being wound into the ice.
With the Revolution Screws we've blended all of those elements to make what we believe is one of the best products out there.
