You want a machete? That's basically what an RTAK is. You can get machetes for alot cheaper and, for their purposes, you're wiser to do so, in my opinion.
Now, if you're after a medium-large fixed blade for under $100, I'd say stick with Ontario, but go to their RAT series. RAT-5 or RAT-7. Even the TAK-1 is a nice knife. All for under $100.....and they're NOT cheap knives but rather solid, functional, affordable fixed blades.
Good luck.
