Pros: Effectiveness, Durability, Overall Quality, Ease of Use
Cons: None
DMT Aligner works great.
I only use the aligner with the six inch bench stones that come with a clear plastic cover. The user is able to adjust the angle to just the right angle using the adjustable aligner. Once the correct angle is determined each stroke is at exactly the same angle, unlike freehand sharpening. This saves time since there are no wasted strokes. Great system. I have had my set of DMT stones for several years and have sharpened many knives with them so yes, they are very durable.
