Right now I'm an apprentice of about a year and a half, but I want to start setting myself apart from the rest of the apprentices that work for my company. Just wondering what tools I should buy that you ended up using all the time and had no idea it would be so useful in the field. Or just tools in general that are lifesavers for troubleshooting or using on a day by day basis in the field. Right now I have a sawzall, impact, hammer drill, portable vacuum, and a ton of hand tools. If it is a badass tool, I don't mind investing a lot of money if it is going to help me tremendously. So putting money aside, what tools would you guys say you like the most! Thanks for your help
