If anything started to peel or crack on blades, I would NOT use them. Remember, these things are spinning at 3000+ rpm and the centrifugal force is quite a lot. If a blade comes off and hits you, it can hurt, severely injure or even, if in the right spot, kill you because of the inertia of the blades. I would replace them ASAP.
Nice kindle to start a fire with.![]()
