Hello, I've been modeling Anakin's lightsaber from Star Wars. I used a Boolean Difference to cutout a circular area on the model. After doing so it messed up alot of the surrounding geometry. Now after trying to fixing and searching all over for and answer, ive read that Boolean's arent that great to use and have alot of problems.

Luckily i save to multiple files alot so its not that big a deal to go back to a save before i did this. But is there anyway to salvage and fix this model? I would like the result if the surrounding geometry didnt get messed up.
