YES
#YES # (Original question was Cleave)
The only Weapon that grants cleave I could find (I couldn't find another item that does so):
Rankbreaker Glaive:
This +2 glaive allows its wielder to make use of the Cleave feat if she lacks it. Furthermore, whenever the wielder takes a charge action using a rankbreaker glaive, he deal an additional +1d6 damage on each successful hit. Moderate transmutation; CL 9th; Craft Magic Arms & Armor, righteous might; 32,308 gp

Similar effects:
- Sylvan Scimitar (as you mentionned)
This +3 scimitar, when used outdoors in a temperate climate, grants its wielder the use of the Cleave feat and deals an extra 1d6 points of damage. Moderate evocation; CL 11th; Craft Magical Arms and Armor, divine power or creator must be a 7th-level druid; Price 47,315gp; Cost 23,657 gp and 5 sp + 1,893 XP.
- The Mighty Cleaving Weapon Enhancement
A mighty cleaving weapon allows a wielder with the Cleave feat to make one additional cleave attempt in a round. Moderate evocation; CL 8th; Craft Magical Arms and Armor, divine power; Price +1 bonus.
