Each blade has it's own tension adjustment screw which you, the groomer, can adjust at any time. Although these blades are expensive, they will save you money in the long run. When you feel that the blades are underperforming, instead of sending them off to be sharpened you can tighten the tension screw and continue clipping. This can be done 3 or 4 times before the cutter really needs sharpened. This prolongs the life of your blades and saves you buying new blades as often as snap on blades.
