Preds wrist blades have been broken, broken by Judge Dredd no less. They aren't even remotely close the strength of Adamantium. The only thing Preds are good for is wiping out fodder. They have been killed or been given trouble by skilled fighters in the comics many times (and when I say skilled... we are talking samurais and 20 year Asian girls with brown belts), Wolverine would take out entire platoons of Preds with out much effort.
