I find myself helping family/friends w/ basic carpentry tasks. Like today it was replacing a rotten windowsill. I had already planed and ripped the stock, I just had to cut it to length at the site, and then profile the ends to fit around the stops, which is quite easy with a coping saw.
But I didn't have a coping saw with me. Home wasn't too far away, so I just went and got one.
But I've been trying to identify the tools that would be the most helpful to have on a jobsite, and just keep them in a dedicated tool bag. And the more flexible a tool, the better. One tool that can replace two is a real plus when you're carting stuff around.
This is really a hand-tools only question, hence the Neanderthal forum. I know when I'm going to need a drill/driver or circular saw.
So do you keep a set of jobsite-only tools, and what is in it?
