Without trying to link to another forum for this information, I compiled a TON of information on tomahawk training over on bladeforums in the Axe, Tomahawk, & Hatchet Forum, complete with a few links to reviews I did on some of the various offerings (I really recommend reading my reviews if you wanna "try before you buy"). Several other members have included their own findings and other links to more available info. With a mods permission, I'll post the link. The entire thread is strictly dedicated to training materials for the tomahawk.
