We know it's confusing to choose the right size blade for your needs. The higher the blade number, the shorter and finer it cuts. For example, size 10 leaves inches of hair which is good for styling short hair and general use. Size 7 leaves 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 so on. However, we strongly recommend that you double-check the specification of your clipper before purchasing. You can check the comparison table for our different products shown below.
