My friend has a laser mag 2000 10", it cut like crap until he put new blades and point on there. The point was the most important. Another friend has a strikemaster with chipper blades that are all rusty and it still cuts ok? I guess his point is sharp although I never checked. If your auger has new blades... I consider welding a new point on there, maybe its the angle of the points' cutting edge, sharper the better. It is hard to imagine the angle of chipper blades matter as much as the angle of shaver blades. I would get that tip razor sharp especially if you thing somebody used it as an earth auger.
