One of the cool features of the scallion is SpeedSafe opening. With SpeedSafe, you can open the blade one-handed. Just pull back on the ambidextrous blade protrusion or push on the thumbstud and the blade moves out of the handle, ready for use. The high-carbon blade steel offers good edge retention and excellent corrosion resistance. The bead-blasted finish makes it easy to maintain. The Scallion's handle is pure stainless steel, which enabled us to build-in a frame lock. When the blade is opened, a part of the handle, or frame, moves into place behind the blade, locking it open and ensuring that it can't accidental close during use. The frame lock is an exceptionally strong blade lock. The second lock is the Tip-Lock. It's a slider that locks the tip of the blade inside the handle until you release it. which ensures the knife won't accidentally open during transport. A great all stainless steel look, blade security, and assisted opening... it all adds up to one great little knife.
