Punch, guilloine, V cut or other

[piperdown]

While we're on the subject, are any of the cheap v-cutters even worth buying. I'd really like to try one before I drop the coin on a Xikar. What's the consensus?

Yes. I bought a cheapie for about $8 and that's what made the decision to get the xikar. Still have the cheap one and use it when I'm off and away.
