Hmmm....
responding to the question "will it work?" I'd have to answer...probably. Afterall throughout history knives of bronze,flint, sharpened bones, and sharpened rocks have worked, so strictly speaking a slab of 420J would probably work...Not because of any intristic value in the blade, but simply the fact that it's a sharpened piece of steel.
That being said, there's no way I myself could recommend the Paratraxx in good conscience. It is NOT a TOPS, Beck,or a Linger, it looks similar, but is NOT. the sawteeth will most likely fall short, the blade is unlikely to hold an edge, the balance will not be the same, due to the Karda..errr...small knife in the handle, it may very well not hold up to throwing. If you want something that you can dink around with and throw around in the backyard, it's probably fine. If you're not venturing far from the beaten path it'll probably do okay. If you want something you can rely on....I'd think twice.
$120 isn't a bad limit for a true survival/outdoors knife, but you'd have to place function above style. Consider Leukus, Goloks,hatchets, khukuris and machetes. If you want a hacker you can throw, consider a decent tomahawk.
All of the knives listed have been around for centuries. They wouldn't have lasted that long if they didn't serve thier intended purchase. For that matter Beckers, Ontarios, and Ka-Bars can be alot of bang for the buck.
The original WSK was designed as a compromise of many things, not especially suited to any one particular task, but quite usable for a multitude of tasks. It does pretty well by most accounts due to the fact that it was well designed and well made. The Paratraxx LOOKS similar, but it's not the same. Just because appearance between two products is similar doesn't mean anything else will be.
If you want a decent blade, I'd consider either getting something more traditional, or saving up a few more pennies if your hearts set on the WSK style.
Sorry if I'm coming off overly negative about the idea, but...that's my input.
best of luck whatever you may decide!
