To be clear, no physical experience with. He was quite knowledgable in what he talked about. And.. he was very blunt, if he thought you were not telling the truth yes he would tell you about it. Bluntly.
I'll give you blunt.
You are clueless. What these guys are telling you about knifemakers not wanting to deal with Cliff's BS is a fact. And don't think that his name isn't well known among them-in a very negative sense. I've been aware of this personally for well over 5 years.
As far as his participation here, over the last couple of years Cliff has become more and more blatant about presenting figments of his imagination as fact. He used to be sincere(IMO), and however misguided some of his stuff may have been, he provided a wealth of GOOD info. I've exchanged emails with Cliff, bought my EdgePro Apex from him, even sent him a knife when he wanted to compare handforged 52100 to that in a factory knife.
That was then.
That changed. He lies. Lies constantly, and attacks anyone who rebuts his lies. What's sad is that if you'd been around here long enough, you'd see that some of the people and makers that Cliff now ridicules are the same ones
that he was asking questions of regarding steels, blade and edge geometry, etc. just a few short years ago.
Maybe the industry-wide acceptance of S30V finally drove him nuts, since he's been crusading against it since before a knife was ever made in it, presenting imaginary facts, and more recently making up outright lies about it.
I'm not sad that Cliff was banned, but I'm sad that his contributions here degraded to the point that he required banning.
