Jackson Rathbone as ''Sokka,'' carrying one of the flint-tipped spears I made for the film. This is a screen capture from an official theatrical trailer that appeared in late March, 2010. Close-up of stone-tipped spears made for the motion picture ''Avatar: The Last Airbender,'' directed by M. Night Shyamalan for Paramount Studios.  The larger one is carried by Jackson Rathbone as ''Sokka.'' Two more flint-tipped spears I furnished for the motion picture ''Avatar: The Last Airbender.'' It should be noted that these ''movie props'' are actually quite deadly, razor-sharp, faithfully-reproduced versions of authentic prehistoric spears.  I also provided extra wooden spear shafts to be outfitted with rubber tips to be used by stunt performers while filming ''combat scenes.'' M Night Shyamalan himself brandishes my spear while directing Jackson Rathbone as ''Sokka'' on the set of ''The Last Airbender.''

Photo Copyright protected by its respective owner Carving process: Wooden handles for the matched pair of ''Hero Knives.'' In the process of wrapping the handles. I experimented with several wrapping variations and materials. This is what the filmmakers chose. It's interesting that they wanted ''doubles'' of everything. In case something gets broken or lost halfway through filming, they need to have a backup. And let me tell you, these things ain't cheap. The show must go on! Matched pair of ''Hero Knives'' for the Sokka(?) character. Blades are DesChutes Dendritic Picture Jasper from Oregon, USA. Handles are hand-carved Curly Maple. This knife design is my own creation, inspired by both Mayan and Egyptian influences. The filmmakers liked the design so much, they commissioned the pair of knives as you see them here. A pair of nearly-finished ''Sokka'' knives with moose antler handles and stone blades. In the background are concept sketches for numerous variations of my ''organic'' design. The filmmakers chose the version you see here, and shown finished below. The finished pair of ''Sokka'' knives, shown with optional decoration at the haft juncture. Jackson Rathbone doing green screen shots on the set of ''The Last Airbender.'' Note my spear and my knife on his belt, featured throughout the film.

Photo Copyright protected by its respective owner This ''Leister'' is made of meticulously hand-carved Elk antler tines on a natural, fire-straightened Hickory compound shaft. For this awesome weapon, the filmmakers asked me to create a copy of an authentic Eskimo fishspear based on a museum specimen. This weapon only appears very briefly inside a Water Tribe tent when the Fire Nation finds Aang. Another view of the ''Leister'' (three-pronged fish spear) along with the authentic museum specimen photo. Note the artificial sinew wrappings were specified by the Property Master for the film. I could have done the fiber cordage just like the Eskimo piece if they had wanted. The customer is always right. More views of the Leister in natural sunlight.  I embellished the shaft with natural fiber cordage and an antler pendant (not shown). The only appearance in the film of my ''Leister'' (three-pronged fish spear), hanging on a wall in the tent where the Fire Nation discovers Aang. Still photo from the set of ''The Last Airbender.''

After seeing some of my weapons, he said he ''loves my work.'' He likes to make ''Hitchcock-esque'' cameo appearances in his movies, like he did in ''Signs'' with Mel Gibson, and ''Sixth Sense'' with Bruce Willis. I wonder if he'll appear in Airbender?
