Wahl's signature 5-in-1 blade is also available in a Coarse blade to make clipping through and trimming thick, coarse coats easy than before. Wahl's 5-in-1 blade features 5 different blade sizes - #9, #10, #15, #30, and #40 - in one convenient blade. What this means is you have 5 different cut length options that range from 2 mm down to a surgical cut length of .4 mm (or 5/64" to 3/128"). You can use this replacement blade with Wahl's 5 Style Groom, Arco, Bravura, Creativa, Chromado, Figura, and any other Wahl clippers compatible with 5-in-1 blades.
