I have some pointers to periodicals that sometimes have articles or other information about knife throwing. The Garvin text contains a few examples of throwing from Peter O'Donnell's Modesty Blaise . Here also in a link to an interesting page about throwing cards that may not be around all that long, so check it out while you can. It relies a lot on the book Cards As Weapons by Ricky Jay, now out of print, but listed in our books page nevertheless. You will find an introduction to AKTA competition rules here.
Membership is required to compete in the annual regional.
There is also a quarterly newsletter. The International Knife Throwers Alliance is another club. This one fostered by Bob Karp . There is a national event held in Phoenix in March. The IKTA competition is much different from its AKTA counterpart.
