The Yella Grapnel($27) is an essential tool for tree climbers or wall climbers. It¡¯s small enough to carry in a pocket or gear bag on every climb(3 ½ inches long grapnel). "It takes inspiration from UK climber Michael Spraggon¡®s idea to recurve the tines for more reliable line-snagging performance. Instead of the simple upward bend of the original tines, the new tines coil around and inward, still leaving plenty of space between tine and shank for the line to enter the coil. At our direction, our fabricator gave us a variety of new prototypes based on this concept. We tested them snagging both throwline and rope. We threw them both right-handed and left-handed. In a trial of 40 well-aimed tosses (not including air tosses), the winner snagged the line 36 times ¨C an impressive 90% success rate! " |
