I grind is in the middle, a little high, the total grinding is not very good, novice, please advise!
The beginning of grinding is like this, the middle height is that you grinding is the pendulum of the wrong angle, the specific angle of the tool, you can look at the shape of the new knife or read the book.Just practice more
The two blades are as long as grinding
Pay attention to the handle,The middle height is caused by the need to grind the back angle, because the grinding of the center of the milling cutter is much more than the sides, so it causes the middle bulge!!!In fact, the milling cutter is concave and the angle is about 2 degrees!!!
