Some really nice pens although for me I am not sure the clip adds to them. The quality of finish you have achieved in the turning is far greater than the clips - I wonder if a more traditional / plain clip would look better?
Also, how do you get hold of both parts of the bullet? Normally the copper bit is a long way away and a bit squashed or do you have a contact in the manufacturing process as I am not sure taking a finished one apart is a recipie for a long and happy career!
