| It looks like the guts of the chuck on a wood boring brace. The spring is there 
to open the jaws so you can put in the bit. There are probably also wear marks 
across the piece on the opposite end from the spring on the angled part. Do a 
search for â??brace and bitâ??.

Hi.  Found this in a tool box.  Does anyone know what this is?  The only thing 
holding these two pieces together is a V-shaped spring.  You can see the end of 
the spring coming through a small hole at the bottom of the picture.  There is 
an equivalent hole for the other end of the spring on the other jaw. There are 
black deposits as well as metal deposits on this, as well as some sort of 
grinder marks, perhaps cleaning this thing up after use.  It looks like most of 
the wear is toward the joined end.  The whole thing is about 2.5 inches long.  
Any thoughts on what this is?
