The scenes in the movie where they threw this thing were pure fantasy. I'm not to sure how practical any knife throwing is, but this knife was not designed for that purpose, and the scenes of it penetrating a sapling are BS. The Tracker knife, while I wouldn't want to get into a fight against it, is not a combat/fighting/killing knife. If you want to see what kind of knives are, run the DVD section on knife fighting and look at the aluminum long bladed, double edged, pratice knives the experts there were using.
The fight sequences throughout the Hunted including the guys with guns in the woods, etc... are as bad for realism as I have ever seen. The Tracker knife is basically a fantasy knife, like the lord of the rings swords, unless one approaches it purely as a survival piece, in which case all the things you aren't asking about mater more than the ones you are asking about.
I'm not being disrespectful. Many people buy knives simply because they saw anyone from Nessmuk, to a movie star using one. For 60 buck the Paratraxx is a great deal for that purpose. I'd be surprised if it turned out to be the real mccoy, but it isn't completely impossible.
The Timber Pig I found online was reviewed by our very own Phil Elmore. I would have thought he could separate a poser knife from one that works, though his article doesn't mention much about edge retention etc... It is clear from the article, however, that the TP was designed with quite different ideas than the Tracker. Actualy it might be a little closer to the role the Tracker played in the movie, since the designer mentions pig sticking. The designer doesn't understand the Tracker knife and for instances calls the draw knife area the hatchet part, and therefore left the actual hatchet part off the knife. On the other hand if the 1095 is properly heat treated there isn't any reason why the edge shouldn't perform fine.
