I have to say yes! I purchased a Mag 9000 this spring. I was hopeful that it would provide me with some time savings when sharpening blades. (God knows nobody wants to spend a lot of time with a grinder and blades following a full day of cutting.) I was pleasantly suprised with the speed of the Mag 9000 blade grinder. I was even more pleased with the quality of edge and cut that my blades had following sharpening. The Mag 9000 grinder is an "investment", as mentioned in previous posts. I have found it to be a worth while "investment in time". It has provided me with more free time and a great finished product.
