I agree that Lie is a strong word thus I have changed the title to "mislead".
While "increase in material cost" and "rounded handles cost more to machine" are most likely true statements in and of themselves, it does not fully account for the percentage of price increases on certain models by comparison. And these statements gives the misrepresentation to readers that 100% of the price increase is due to these reasons. Manix 2 vs Shaman for example? Both S30V and G10 made in the same factory, yet the price difference is astronomical.
When you sign up for apps and facebook etc and they tell you they wont' sell your personal information do you believe them? Every last company that collects your information sells it. Did you know the DMV yes, the government operated DMV sells your information? I would not trust 100% the owners of companies who stands to make a profit from YOU and their explanation to price increases. It's called a conflict of interest! Is anyone really going to say "yes, we feel this knife model is very popular with insane demand and thus we're going to charge as much as the market can bear to maximize profit"? No, that's a PR disaster and no one in their right mind will say that.
I'll repeat what I stated in the original post, I believe there is nothing wrong with maximizing profit. It's the altruistic pretense and and when anyone questions it like I did they get beat up that's upsetting.
So at the very least, I believe "mislead" fits better in this situation.
