Anybody Here Use a Machete in Gardening?

[NJCher]

One of our gardeners at the community garden used one last year. I was kind of impressed, so I bought one.

I tried it out on my wisteria but was not impressed. Maybe I should sharpen it myself. 

If anyone has advice, I would like to hear about what you use it for.
Do you think a brand new machete should need sharpening immediately?
Do you consider it a timesaver?
What kinds of plants do you use it on?

When I bought it at the local hardware store, there were some guys standing around waiting for their turn with the owner. One of the guys looked at me carrying my machete and he asked what are you going to do with that thing and I said "cut some mint."  They all looked at each other with alarm. I said what's the matter?  You don't know what mint is?  Then they laughed and said we thought you said you were going to cut some men!
