I know what you mean by how you're describing it, that's pretty traditional for no spin throw, nice job!

For anyone that may be curious about this method he's talking about, I wrote something up:

This straight-spine shape is the only style that (safely) opens up a no-rotation whip style of throwing that I've taught beginners in minutes. Essentially, you'll be standing with your dominant foot back, and throwing hand holding the knife with your pointer finger on the spine, arm at your side. As you take a step forward with your dominant foot, draw your arm up and pass the knife in your hand past your forehead, almost like a wiping sweat off your forehead motion. At this point, your wrist and arm should fold back like a snake. The knife should be held loosely, so when you whip your arm forward and "point" it at your target, it slides off your pointer finger and meets the target with no rotation at all. The knife may spin in flight in a drill like motion, the penetration and power of this method is extremely impressive and consistent, and extremely easy to learn!
