Seve[wiki=]ral years ago I made a mountain man knife sheath, compleat with  2 peice brass rivets, a male and female halves, if you will.
 
 I can't find any where to buy them , Tandy has Cones? and dots? but the dots look to be about 3/4" . I was hoping for 1/4".
  Any ideas where I might find them?  and what are they called?
Thanks
