However, I'm going to play Devil's Advocate for a moment...

Definition #1 seems to apply.....so....if talking about "virtual fixed blade"......and apply it to the definition mentioned above...
"converting a folding blade into a virtual fixed blade" might simply mean "locking the blade makes it as non-folding as a fixed blade, though not actually or expressly."
Well, isn't that true to any locking blade by any company? What about rat tail tang fixed blades? The whole, "catastrophic failure if significant pressure is applied....."....We all know the same applies to that style knife and it is considered a fixed blade. I'd wager my 16 yr old daughter could easily break a rat tail designed fixed blade...I KNOW I have already.
And for the record, I wager that I could have no problem breaking a CS lock, touted as "the worlds strongest lock." Any mechanical lock is subject to failure...So should CS be sued in that case?
