Kershaw's Ion is a set of three throwing knives-plus a convenient, nylon sheath for storage. We have to admit it; throwing knives is fun. But throwing just any knife is dangerous-and not very smart. To throw knives, knives specially designed for throwing are required. That's why Kershaw made the Ion Throwing Knife Set. The three knives in the set are designed to have the correct weight and balance for target throwing. Kershaw's Ion knives are double-edged, spear-point blades. We made these full-tang knives from sturdy, high-chromium stainless steel and wrapped the handles in durable, sure-grip paracord. The extra-wide ring at the end adds balance, offers a great place to attach a lanyard, and makes it easy to remove the knives from the sheath-or from the target. All three knives fit neatly in the nylon carrying and storage sheath, which makes it easy to take them out to the throwing range.
