Spiral Fracture of the 4th metacarpal in the right hand, requiring two titanium screws to repair. Auger bit in the D-handle Milwaukee drill twisted out of my hand because I was too lazy to attach the side bar. No blood, but lots of time not cutting timbers. Still have the drill... and the screws :-)
The most dangerous tool in the shop is the one in your hands!
Have fun with Sketchup, Derek.
