I like it for the fact that it's silent. Silence is an integral part of DayZ for people who play alone. I hate firing my weapon - if I do it in Elektro while hitting up the factories for parts, well crap, everyone knows I'm here. Maybe we could combine ideas. You could either swing like a madman - a 1 shot if you hit the neck or head, not if you hit anywhere else - or you could assassinate, which requires the target to hold still a moment longer. Now it's a dangerous and tactical trade off that you need to think about. If you pick the wrong one, you might die. I just think a little throat-slitting animation would be more realistic than just swinging like an idiot and watching them die. Maybe if you go to assassinate, the other player has something like a .5 second chance to click to interrupt you. That way, if they see you just before you do it, they can definitely stop it. But if it's an surprise, they wouldn't react fast enough.
