The blade didn't even cut in, the suit being four times stronger than steel thanks to a real life alloy that's a mixture of steel and gold. It did sting like hell however and probably left a bruise. Under the alloy, a magnet repulsed the blade the second it hit so hard the sword would easily fly out of the hands of a normal person. In the mean time he used his other arm and the strength of the suit to slam the staff into his opponent's knee.
