Aside from a few scraps from the concrete, the hilt and blades have held up great. A bit sad that one of the extra blades that I ordered has had it's diffuser removed (my oldest son) and then crinkled up before being shoved back inside. That's okay. I plan on putting one of them thru a series of laboratory testing soon, guess it's going to be that one.
kids do the darners things , not a perfect replacement but florist cellophane rolled up on a dow rod is a cheap fit
