Yes, Somewhat true, If the knife you're interested in is a past offering like an NMFBM or NMSFNO etc... You have to watch the "Busse, Swamprat & Scrapyard for sale" forum for someone to sell a model you are looking for, But that's hit or miss. If you send an e-mail or private message to Pokey1 and request to be added to their e-mail/news letter list, You'll receive and e-mail when new models are being offered, They will usually be offered in a "Gaaannzzaa" pre-designated date and time and then possibly added to the Busse website after the Ganza, But not always, The NMSFH and NMFSH LE were only offered through the Ganza so if you missed it, The only possibility is if someone who did not miss the Ganza decides to sell theirs.
As a matter of fact, An e-mail just went out today about the newest offering called The Tali-wacker, The Ganza is the 25th of this month between 9 and 10PM.
Message Pokey1 in the Busse Combat froum and she will probably send you the Tali-wacker e-mail.
