From Bulbapedia, the community-driven Pokémon encyclopedia.
Klutz (Japanese: ぶきよう Clumsy) is an Ability introduced in Generation IV. Prior to Generation V, it was the signature Ability of Buneary and Lopunny.
Klutz prevents the use and effects of the held item of the Pokémon with this Ability.

It has no effect outside of battle, so items such as the Cleanse Tag and Scarves are not affected.
Klutz does not prevent the user from using Fling.

Klutz does not prevent the Pokémon with this Ability from Mega Evolving with a Mega Stone or using a Z-Move with a Z-Crystal.
