We know it is confusing to choose the right size of blade for your needs. The higher the number on the blade, the shorter and finer it cuts. For example, size 10 will leave inches of hair which is good for styling short hair and general use. Size 7 will leave inches of hair, which is recommended for use on matted fur. A5 snap-on blades fit most other detachable clippers on the market such as Andi AGC AGC2, Wahl KM2/KM5/KM10, Oster A5/A6 and etc. However, we strongly recommend that you double check the specification of your clipper before making the purchase.
