If you’re having difficulty cutting or it is pulling at your pet’s skin in spots, then chances are the blades have become too dull.
On average, one blade should last 4-6 sessions of use before needing replacement. While this may vary depending on the type and length of fur/hair you’re cutting and how often you use the blades, it’s essential to know that a sharp blade is easier to cut with and causes less stress on your pet.
