Fox Knives does it again with the radius, and back to back Blade Show Knife of the Year awards! Designed by Denis Simonutti, the Radius features a new lock that takes major strides in the directions of safety, ease of use, and fidgeting. To open, use the stud to rotate around the pivot, opening the blade. To close, just push down on the stud, and rotate it back. The Radius is a statement of a knife that will bring a smile to your face each time you open it!
