machine - I wrote a reference book on Randall Made knives that is sold at the Randall Shop; so, some would tell you that I know a thing or three about them (I, however, wouldn't - I just answer questions for free).
That said, I don't speak for the Randall Shop, nor do I have much contact with them other then selling them books and buying their knives. Thus, all shop related questions, IMO, should be asked of the shop. Via phone at 407-855-8075 or via the email contact page found at
http://www.randallknives.com/ I'd suggest you ask for a free catalog while you're at it.
As to sales; yes, I resell Randall knives on the secondary market, but don't advertise that fact here on Bladeforums.com (BFC) because I don't have a dealer membership. In fact, I kinda cringed a bit when Dan, aka zaptain mentioned my website, in that my 'support the forum' Gold membership runs me about $35 bucks or so a year - while a 'dealer' membership runs ~$600 a year last time I checked. Like you, he's new here and doesn't know all the rules yet...
I do have the ok to run the book announcement in my Sig line, however, because I offer free domestic shipping (on the book) to anyone that mentions and can show they are a paid BFC member in good standing - as a perk to BFC members. Typically, any knives you'll see me selling here are my personal, used, low cost EDC knives. When I said I could help, I meant that I could steer you in the right direction - not that I had something to sell ya.
That said, as to the Saw Teeth / No Saw Teeth (ST/NST) Model #18 I have - that's a pretty rare bird. Sawteeth are standard and free on a Model #18. The ST/NST option (to do a special order knife with no saw teeth) costs an additional $35 and is not mentioned in the catalog. As such, I've seen exactly three configured like that in the last 11 years, and I've owned two of them.
Hope that helps :thumbup:
