Convex Lens adapter [7.2 degrees only] (In stock)

The convex lens adapter lets you create a repeatable convex edge on your knives.  Typically this would be for choppers and survival knives, including parangs and goloks (think Fallkniven A1, Bark River Golok, or Condor Mini Duku).  The limitation of the adapter is it only lets you create a 7.2-degree change in the convexity.  If you want more adjustments, buy the universal Convex Lens Kit instead.
