Every once in a while, I get a new tool or piece of gear that makes me ask "Why did it take me so long to get this?" My tool belt - pictured below is one of those things. When I'm working on an assembly, I can have all of the tools I need readily available instead of walking all over the place looking for something I set down in another location. I keep clecos in different pockets along with markers, my ruler, clamps, a deburring tool - all kinds of stuff. When I go out in the garage to start a building session, I strap it on and have everything I need right there. Duh.
