I reground the edge to 25 degrees each side, which not only makes it very easy to maintain the edge, but it cuts whatever you expect it to cut, again , again and again ...
The edge on the left is the factory edge, the new edge is on the right. I didn't bother to give it a mirror edge because its gone in the first strike, but I am so happy with it, I bought another as back-up so I don't have to pay exchange prices.
