For un-doing idiot knots a marlin spike works better. If you are
going to be splicing 3 strand then a fid would be usefull. I never
used a fid on anything smaller than 3" line, a spike like I posted a
link to is perfect for splicing small stuff.

I use a screw driver most of the time. Sometimes
I take an old chewed up screw driver and grind it
smooth, but even a good screwdriver works well.
