I have the NRG, and will second the notion that it will do the job it was made for. Despite its size, it is very light. And besides that, I heard you can sharpen it to a pretty decent edge, enough to cut at least once or twice b/f you finally stab the bastard. Anyway, it's worth $20, as opposed to whatever the horrible price is that Mad Dog charges, though I wish I knew what Szabo's Glo Knives look like and how much they cost. As for the Executive NRG, I've heard nothing but good things about it in all aspects of judging a knife's quality.
