You are correct sir with the 1st pic.

Even with a buffing wheel, the blade edge can quickly "grab" the wheel and the results are generally disasterous to a blade (and the wheel)! This problem is magnified if you are working a spike point and get a little too close to the point!

I will try to set the blade flat on a smooth surface (an old flat board) and work from the spine down toward the edge. Always work slowly and ALWAYS be aware of the direction of rotation!
