9 BLADE - This is one of the finest knives and enables drawing of short rounded hair. It does not reach the depth that the other knives do, so it is ideal for filling small gaps and use in connection with larger knives.
12 BLADE - This is the most common blade and can be used throughout the treatment. It can also be used with the 9 blade to achieve perfect brow hairs and bends.
14 BLADE: This blade is slightly thicker than the 12 blade and makes it possible to reach the depth needed for the hair to hold. However, it is more difficult to achieve a bend. Straight hair can be pulled with this blade and it is ideal to put the initial structure in or alternatively for the second or third set.
U14 BLADE - This blade is in rounded shape and is especially for curved lines and rounded shapes. Lines can be drawn in both directions with this blade. However, it is recommended not to do the entire treatment with this blade.
