the only experience I've had with PM steel is from my Lee Valley plane irons. I like them, and find they retain the edge considerably longer, but initially found them a little finicky in creating a burr. With that said, its for woodworking and not shaving.

I'm also on the fence about the damasteel. I love the look but, there is a part of me that feels that the look of a W&B should be traditional. I'm glad to see that they are offering three options, with one being mirror polished. ..... SO EXCITED!
