Give them at least it didn't melt this summer.
Maybe a JB Weld' fix. Hmm.
Vaco used to make a good one, but I think they are owned by Klein now. I use one of the Klein 10 in 1's for the light duty first response stuff and have a mixed full set of Klein and Craftsman heavy duty drivers in my toolbag for the real work.
Here's a link for the Klein replacement bits: http://www.mytoolstore.com/klein/32477.html
They only have the original replacement bits. I wish they had different ones available. I don't think I've ever used the square bits and would like to replace them with a 20/25 torx bit.
I could NOT find a picture by itself, so I had to use the link.
I like these. The bits are as hard as h**l and work well in my drill and Dremel driver.
That's my favorite multi-tool. I still keep long 1/4 and 5/16" magnetic nut drivers. Every other tool has a specific purpose except the speed square and that thing does everything else...
I laugh when I see a tech bring out a multi screwdriver, then I say real techs have the proper tools to do the job go get your tool bag and stop wasting my time.
