You can always go over to
http://www.cssdsc.com, register for Bram Frank's forum, and talk to the man himself. He should have some DVDs for sale that go over the basics of the system or you could register for one of his seminars. The Lapu Lapu Corto is Bram's current incarnation of the Gunting, and DVDs concerning its use are available at
http://www.cherusker-messer.de. The company is in Germany and the website is in German, but they have an "English-speaking customer" page and take orders from the U.S.
I have multiple Guntings and consider the design to be outstanding. I regularly EDC (when not in a business suit) a 440V plainedge Gunting. If you decide not to contact Bram or buy the DVDs, email me or PM me with questions and, when time permits, I'll do my best to answer your questions. A seminar with Bram is your best (but priciest) option, followed by Bram's DVDs.
