As it stands now, PCKS will only customize 110's. There was a lot of discussion towards the end of last year about PCKS offering more models in the future. Since they revamped the software that Pete's Custom Knife Shop uses recently, I am hoping they are now working on adding more models to the options. The 503, in my opinion, would be a good canditate along with the 500, and my personal favorite (at the momment) the folding Alpha series.
Joe - any update on when PCKS will fancy up more than just 110's ????
