Just got one of the same feathers and blades myself for my birthday in September. They are lazer sharp but a little palm stropping will soften the edge. As has been said a couple times pressure is a big point. You only need contact not pressure. The blade will do all the work you literally just want to kiss the skin and float over it. Do basic strokes and finish with the de till you have the feel for it and add more as your skills grow. Good luck
