We needed a walking chisel, so decided to make one.  It needed to be made of harden steel.  This car spring was perfect for what we wanted.

I'm a bit of a wimp when it comes to sparks flying when DH is cutting metal and I usually take off to a safe spot (the other end of the basement lol). Not this time!  I had to hold one end of the spring, so DH could cut a piece from the other.  It was a very long 30 seconds or so, as the sparks were flying higher and wider than in this photo.  

In this pic, DH was cutting a piece of steel for one of the key fobs below.

This is the chisel and it works great!

We were mucking about with the chisel and tried a pineapple twist.  We like the twist, but doesn't suit a key fob, as for the pattern to really show, the piece of metal needs to be longer.

We also tried an alligator twist.  As above, it needs to be worked on a longer piece of metal and it needs to be thicker, too, to make the pattern show.
