Out of 21 Spydercos I use pretty much all my Spyders regulary.
probably my most used Knives are my Militaries.
my least used are a SB Caly 3.5 - i love the look and the aesthetics of the model, but somehow i do not carry it often. And a very old SE SS police. This one i don't carry often since it's rather intimidating looking and non knife people reacted a little weird when i used it.
Also i've a NIB PPT Sprint in CF and S90V i'll be willing to sell if i'd get the money i spent when it was released and i panicked to get a hold of one so i ordered 2 by mistake
