nope nothing , there are a few pictures in the gallery that happened in the first 15 minutes but I did run the rest of the weekend like that both tip chipped off, it is also a flat foil blade (old style) they don't have any cup in the blade like a sensenich does.
Like was said earlier , my opinion is the price was one of the best around (but as others said that I get what I pay for) I think his blades would be fine for lower powered mini
