Impossible to use in heavily compacted soil

Good sturdy construction. However, the ends of the coring tubes are flat (perpendicular to the length of tubing) and the edges are rounded off. Basically, this will not break soil that is any way significantly compacted (which is the very soil that needs aeration). For that reason I cannot recommend buying this. I am going to attempt to grind the points at a 45 to create some kind of point that can penetrate soil. If that can't be done, then this thing is a total waste of money.
