Orko,
not sure who designed it first because it could of been either Bob Taylor or Randy Wanner or both. Michael Echanis had some input in the desgn too. I use to own two of those knives. Sadly they are gone now. First off, the knife is to be used in the "Reverse grip" method of holding knives. The inner edge will be where the serrerated edge ( I use "serrerated" very loosely here because it is not a true serreration) is used for ripping and/or scaling the victim. It makes a terrible wound on the victim when used like this. Secondly, it is not reccomended to be used in the forward grip. This knife is a slasher not a stabber. Too many thrusts into the body will create a stuck knife into bone and/or between bones, hence the great curvature of the blade. Thirdly, this IS NOT a survival knife, period, rather this is a "Fighting Knife" only! The original name for this knife is the Hobit Warrior IIRC.
