I have the super duper named 0452CFBLUBLKM390, it's nice but ended up not being used much because I was iffy about scratching up the DLC on a Sprint Run.
I completely understand.
What I cannot fathom a reason for is ZT, Spyderco, Buck, etc., not making enough sprints / factory customs, when they do make these knives. It's like they are afraid to have 25 of them sit around for sale for a year.
I'm on the Spyderco Forums and I've asked repeatedly for a Custom Shop, where people over a six month time period could order a knife with special steels. For the most part, nobody wants to chat with me when I bring that subject up. IT'S ALL A SCAM to inflate prices of objects and a complete line-up that are not intrinsically valuable. They have 3,000 people interested in every special product so they make 500 and keep you pissed off and raving mad to get one.
