Enjoy the absurdly-named exotic weapon, the
Dragonsplit
Appearing the Monster Manual IV in the Greenspawn Sneak entry, the dragonsplit
can be used as a piercing weapon like a short sword. Alternative grips use its long edge for
slashing attacks or its short edge for chopping and hacking. It counts as a light weapon for the purpose of Two-Weapon Fighting and Weapon Finesse. (151).
A Medium wielder employing this 2-lb. otherwise-one-handed1 exotic weapon can choose, before making an attack, to inflict either 1d6 points of piercing damage with an 18-20 threat range or 1d6 points of slashing damage with a ×4 critical multiplier. It's for D&D 3.5 but, strangely, no price is given for purchasing one.
I always imagine the dragonsplit looking like an oversized balisong, although the official depiction is far different. (The greenspwan sneak on MM4 149 is wielding one; it's just a weird-shaped blade.) Picturing it as a big butterfly knife is the only way I can make the dumb name acceptable in my head.
- Yeah, I know. So, if one is so inclined, with it one can use the feat Power Attack (PH 98).
There are two sections to the attack line, a name, and then the stats. I’m going to format the name in bold and the stats in italics:
longsword +5 (1d8+2/19-20)
Thus, the name of the weapon – which weapon it actually is – is just “longsword.” As in the generic, unmodified, non-masterwork, non-magic longsword (stats in the “One-handed Martial Melee” weapons table).
The stats, by the way, are attack (+5), damage (1d8+2), and critical (19-20, the range; a multiplier of ×2 is implied). These stats are all totals, after all factors are applied, so that DMs can just use them as-is, without having to hunt down other relevant stats (and possibly miss something like a relevant Weapon Focus feat).
the +5 attack comes from a combination of BAB, Strength, and possibly something like Weapon Focus
the damage comes from the weapon itself (1d8) plus other bonuses like Strength
the critical stats are from the weapon, but can be modified by e.g. Improved Critical.
If you were dealing with a magical weapon, say a +1 defending longsword, the statblock would instead say:
+1 defending longsword +6 (1d8+3/19-20)
Note that the name is still bolded, it’s simply also italicized to be consistent with the formatting used by the books for magic items. Note how the +5 attack bonus is now +6 (because of the +1 enhancement bonus), and the damage is 1d8+3 (again, +1 enhancement bonus).

Scythes do not have a stat block in 5th Edition D&D
Whether you're a DM looking to issue a Scythe to a player, or a player trying to convince your DM to permit your character to use one, you'll need to roll your own statblock for it; there's neither a Mundane nor Magical Scythe to draw from.
My recommendation is to use the statblock for a Glaive or Halbard (which are the same)
The reasons for this are that it's most likely to give you a weapon that resembles the classical manner in which a Scythe is used* in combat:
I would probably disallow gaining benefits from the Polearm Master feat though, since a Scythe is pretty unlikely to function the exact same as a Polearm, in terms of how it is swung.
* In Fantasy Fiction. In real life, Scythes are notoriously difficult and unfit to be used as weapons, and if D&D were attempting to recreate real life combat 1-to-1, Scythes would probably have a very poor statblock to capture that issue.
