Icicles, the slightly smaller version of the Dry Ice Tools, are designed to be used as Indoor Ice Axes that work by looping stiff rubber straps over the holds used in rock climbing gyms. The climbing motion is exactly the same as when ice or mixed climbing. Now you can prepare for the upcoming ice season, in your gym, without worrying about injuring someone or puncturing the pads with sharp points raining down from above. Icicles are great for youth just getting into the sport of ice climbing, or for anyone with smaller hands.
