Man, does it ever end?

The problem of maintaining a constant angle as one approaches the tip of a curved knife is something that vexes many knife sharpeners. I try to demonstrate the correct way to follow a curved blade by using a 'Mock Blade' ground to a 45 degree angle on one side and extra extra thick. On this visual aid, I've marked the blade with marks perpendicular to the edge along both the straight portion and the curved part of the blade as a further visualization to help 'get' how one does this task.
I demonstrate the simplified approach - put the abrasive surface at the angle you wish to sharpen and hold the knife in a horizontal plane. Then I demonstrate if the abrasive surface is horizontal how you do the SAME motion, but in this instance it looks like you are lifting the knife up. I feel that maintaining the knife in a horizontal plane and rotating it is a simpler motion to perform and results in greater accuracy.
There are many people who describe various contortions to achieve this simple highly repetitive motion, referring to 'lifting the knife' , 'twisting the knife' and various confused descriptions.
I hope this clarifies the basic geometry behind the mechanics of maintaining a consistent angle around the curve as one approaches the tip.
Hope you guys like my first knife design, LOL It's a style that will be a big hit on KKF where they might actually think that I made a knife.
