Cold Steel Throwing Knives
Cold Steel, inspired by the original Tru-Bal throwing knives bring you their own blades. Harry died a number of years back but his contribution to knife throwing is still blessing many new knife throwers today. The Cold Steel versions are robust, affordable and readily available.
Cold Steel Throwing Knives from "Cold Steel UK" website:
Pro Balance, Perfect Balance & Sure Balance
As you can see, these are definitely McEvoy inspired. They can be obtained from Cold Steel UK or Framar Knives.
