The ATAK is definitely a more purpose-built knife, so if you are going to buy a "fighting knife" and only expect it to excel in that capacity, then go for the Mad Dog. IMHO though, the Busse is a better deal, INFI spanks O1 in toughness and the warranty is BULLETPROOF. The Steel Heart is a more general utility blade but Jerry stands behind his knives 100%, he will replace it even if you were trying to break it.

You gotta be kidding me, right? I think it is a REAL stretch to say that tactical forums, which are run BY KEVIN MCCLUNG is somehow more balanced than these forums. I refuse to visit that site after I saw how unprofessionally Mr. McClung dealt with a warranty issue, in which he insulted his customers. In that episode I saw how a REAL "operator" works, by insulting a customer that tried to prove to themselves that Maddog knives deserve the mountains of hype that they seem to have. I also take issue with how he treats competitors, like Mick Strider and Duane Dyer (sp?), by insulting them and essentially calling their designs useless. All of this in a forum in which he dishonestly deletes posts and allows his buddies to gang up on his own customers. I am sorry but I don't care how good his product is I refuse to touch another Maddog thanks to his obnoxious and condescending attitude. I am not trying to start a flame war but I can't believe that a guy with his attitude is still in business.
