Let me clarify that- I meant to ask if they only sell one type of knife at a time, I'm pretty sure they'd only release one at a time anyway unless they debut a new line or something. I noticed there is a pretty good little selection under the knives tab on scrapyard's site, but then in the ordering tab all that you can order is the scrapper 5 LE.
yeah one knife model run at a time. although the secondary market has a great selection if you know where to look.
