I need new blades. At first I had Coronation Aces then Hans Gerschuilers. I want a blade that hold its edge well so I don't need to sharpen them as often. I found that the coronation aces did not hold there edge as well as the Hans Gerschuiler. I was considering Wilson of MK. I am not a high end skater but want an edge that lasts. Could you tell me what blades you would recommend? Also what do you think of parobolic blades?
I don't have experience with parabolic blades, nor am I familiar with different metal in blades. How you take care of the blades is more important for holding the sharpening than which blade you choose. Sorry I couldn't be more helpful on this subject.
