Honestly?
Kinda too much, yeah
They're built well, so if you get it, it'll last for you.
It's just that it's past the dollar figure where it makes sense. You can get sturdy, reliable knives for about half that nowadays. Even with cold steel having shit on their warranty, there's options from them that are just as tough.
That being said, if you're into that design, there aren't really any that are similar enough to match it, and Demko for sure designs usable knives that also look cool, so that aspect is difficult to quantify in cash.
And I'm not saying this because spending big bucks on knives is a hard no. I've spent more than that on knives, for the exact reason I just mentioned; sometimes there's nothing else that fits all the design parameters, so you either pony up or do without. I have multiple benchmade 710s because that design fits my hands and preferences perfectly. And I paid through the nose for most of them (excepting the original).
I'll also say that if you can, finding somewhere you can handle an expensive knife before buying is a great idea. Buying on looks on a screen and the specs without handling it, any knife could be a disappointment.
