I was wondering if there was a specific cost, damage, weight, and other properties for a machete as a weapon in 5e. The Player's Handbook doesn't have anything listed for it. I've also been trying to look at the D and D wiki online to see if I can base the stats off another weapon, but I can't reach a consensus there, either. Some say it should be 1d8 slashing while others say 1d6, and they also have weapon variants listed for both scimitars and handaxes that are similar to machetes. Any advice?
5e isn't particularly comprehensive with it's weapon categorizations, but it doesn't particularly care to be, either.
I'd probably take the stats from hand axe over scimitar. Machetes that I've used have been short chopping tools that rely on their weight to aid the work. They work more like a very broad-bladed axe than a knife. I'd not consider them a weapon you could use with finesse. However, they've also been gardening or trail machetes, not weapons of war.
That's really all you're deciding here. "Can it actually be used with finesse?" If yes, then scimitar, else, probably hand axe.
Scimitar is probably the closest match, but looking at how machetes are used it's not a very good one.
I would argue that it should be a simple weapon (used almost exclusively by farmers and such) that does d6 slashing damage and is not a finesse weapon (they are generally balanced towards the end of the blade for stronger chopping power, not really nimble when used as a weapon). It should also be quite cheap.
