$220 for a custom fixed blade in 3V... Thats planned for EDC, its in transit right now... Also have a ZT301 in transit that I paid $198 for...
Currently my most expensive EDC is $150... Several of my knives fall into this price... A Kershaw 1580MC multicolor Boa, and a custom fixed blade in S90V. I used to have All black Boa in 440V that I paid $250 for in 2001-ish and EDC'd but it was stolen.
All these knives provide more than enough function for me in EDC so I find it very hard to justify much more expenditure than that. I think it'd be interesting to also know what is the least someone has paid for a knife the love and EDC.
