Superb!
 
 Were you trying out a new Christmas pressie? BTW is the camera expensive? It would be very cool to use such to film some sword sparring, not to mention other sling-related themes!  

nice  
 
What sort of distance have you worked up to ?

Who else has experience with these?  
 
I personally find great joy in both throwing them and sparring with my buddy. Overall I think they're a very versatile weapon in a hand-to-hand combat situation. They can be used to defend against a variety of other weapons including knives, swords, and clubs. With a lot of practice in both muscle memory and judging position on instinct, one can also become very formidable with a throwing tomahawk... Even while moving.  
 
I own two modern SOG Fusion Tactical hawks and three handcrafted, replica 17th century wooden throwers. I find it hard to choose which I enjoy using more. The SOG hawks are weighted for throwing and are also very tough. They're great for learning to throw from longer distances and they can take a serious beating. The wooden ones on the other hand, they throw like a dream and have the heft to drive the blade pretty deep into a target.  
 
One more question, does anyone have experience making and/or using stone tomahawks? I am interested in having a go at crafting one myself.

If you like hawks you need to look up vec hawks they are the best

I think they run 250.00 but he garentees it

Here's mine.Designed by me,forged by a blacksmith. "scythish-hunish" shape:

Been a long time 'hawk fan. I have a customized CS trail hawk and the sog fusion with innertube sewn over the handle (I thought the handle was a little small).
 
My Dad did his Kenpo Black Belt Thesis on adapting Kenpo Techniques for use with a Tomahawk and a Knife. It was pretty awesome. He has the CS trench hawk and a plastic trainer.
