An ice screw is a device used to protect a climber when climbing on ice. Ice screws are tubular in shape. Common sizes and weights of ice screws are 12 to 22 centimeters in length, however shorter and longer screws can be found. Ice screws vary in weight by the size. Shorter ice screws are around 6.5 ounces, and the longer ice screws are about 8.5 ounces. When placing the screw in ice the tip is subjected to a lot of force. This dulls the tip over time. The newer, more modern ice screws often have replaceable tips. Some ice screws have a variety of features. Some have a separate crank for screwing the device into the ice, while others have an integrated handle and hangar. Attachments for clipping will either integrated into the crank design, or as a separate appendage to the screw.
Grivel 360 Ice Screws
More...The Grivel 360 Ice Screw uses its unique folding wire handle design to allow fast placement in pockets and corners where other screws can't go. Give the 360 Ice Screw a few twists to get it started, then flip out the handle and crank it home with ease. Its large handle requires less energy to crank in than little handles, so you save your strength for swinging tools. The Grivel 360 Ice Screw also has a low-profile square hanger that fits into small constrictions, reducing the need to clear ice before placing.
Petzl Laser Sonic Ice Screw
More...The Petzl Laser Sonic Ice Screw is the latest innovation in ice climbing anchors, and perhaps an attempt to push the envelope beyond the current leader, the Turbo Express. The Laser Sonic is designed with a rotating hanger and crank-in-one for ultra-efficient placement and removal. For the leader, placement is possible with one hand. The aggressive teeth bite into the ice for optimal penetration in as little as one and one half turns. The increased angle of the hanger away from the head of the screw means less effort scraping away ice and a quicker overall placement time. During cleaning you can leave the screw clipped to the rope, reducing the risk of dropping the screw.
