Mr. Sinister
In the FF/X-Men crossover some X-Men had their powers mixed with that of the FF, Wolverine had Reeds flexible body. He dodged all of the Human Torch's attack, wasn't phased by Storm's lightning or a punch from the Thing, but could NOT harm Thing either, he did manage to almost stab a flying Storm, but just missed her & ripped her clothes instead & flung her to the ground...He flung Thing through a bunch of trees & was strong enough to throw some boulders at Thing & Cyclops as well...
Thing picked up a tree & launched it at Wolverine, Logan turned his body into a bunch of ringlets to avoid being hurt, but with a full blast from Cyclops, Wolverine gets knocked out...
Thats just a short version of what Wolverine did when he had Reeds powers mixed with his own & apparently he can keep his claws hard/sharp regardless of the rest of his body & even extend them further
