I guess I'm most profoundly influenced by nature. Artist-wise I'm pretty obsessed with all things Art Nouveau, Hector Guimard and Victor Horta above all. I really admire HR Giger's work and of course Albert Paley's early forge-based work.
As far as the blacksmithing itself, it's pretty basic stuff. The gate I attached has a lot of pass-throughs and collaring, but for the most part my work is just a lot of tapers, some upsets and a few twists and textures. My main focus is on line and composition, forged steel really lends itself to this end. I work out of a small shop, nothing too stellar tool-wise. I rarely work anything over 1" square so my 50" Meyer Bros. hammer does fine, not that I don't have fantasies about a bigger pneumatic hammer!
I generally work off a loose sketch and improvise a lot of the work as the pieces progress. This can be problematic as "sketching" in steel is different than on paper, but it always leads to happy accidents and ideas I just can't can generate in 2D. Mostly I try to have fun and do some justice to this craft we all love so much. :)
