To evolve Sneasal into Weavile you have to level it up at night (Hour 20:00-4:00 according to your Pokegear) while holding a razor claw. You can get a razor claw at the battle frontier for 48BP. Hope this helped :) -Karissa

Well this is kind of obvious, but you train it! I mean, it's that or you evolve it through trade. It's simple enough for anyone! This answer that was first posted is completely wrong. You have your sneasel hold a Razor Claw and level it up 8:00 Pm to 3:59 AM.
Sometimes held by sandslash, sandshrew, sneasal
