Yes! The upper blade is easily sharpened. However, the lower blade is serrated to grip fine fur, so we do not recommend sharpening it.
If you can brush them, you can SCAREDY CUT them. When first acquainting your pet with SCAREDY CUT, let them sniff the comb and then brush them gently. This way, your pet will greet your SCAREDY CUT as a familiar friend!
Not at all. Dirty fur will dull blades over time and so our professional advice is to bathe your pet first. However, we believe that your pet's comfort and happiness is ALL that matters, so groom that dirty fuzzball whenever it's a good time for them.
