Only very, very recently in man's long history of using tools to process wood have "knives" become considered as one of those tools. If you pulled out a knife like most of the current "choppers" and chopped (or batonned) with it in front of one of the pioneering woodsmen who settled this country....he would have looked at you like you were a inexperienced knucklehead.
All that said....big knives are big fun. Depending on which kind/thickness of wood you are gonna have a grand old time bashing the bejeebus out of, get a big bombproof thing like a Becker or Ranger (hard/thick wood), or get a machete or leuku (softer/thinner vegetation/wood), etc etc etc.
Get what appeals to you in a what you feel is a reasonable price range, then go beat the snot out of it. Goggles are a very good idea.
