Fox Radius Lock Purple Fat Carbon Folding Knife [FOX550CFPA]

The 2019 Radius breakthrough

Denis Simonutti’s Radius was introduced at Blade Show in Atlanta in 2019. Fox records that it received both Imported Knife of the Year and Overall Knife of the Year, with the patented locking mechanism at the center of the design’s recognition.

The circular button assembly is a visible part of the knife’s identity. It organizes the opening and closing movement around a rounded pivot housing, giving the handle an immediately recognizable profile. Different Radius editions use different steels and handle materials, but the mechanism is the common design idea.
