Did you accidentally make the wrong piece of armor?  Do you want something to do with all the horse armor you find?  Do you need more metal to build something?  Then paste this command into your world!

Hey PlanetMinecraft, this is Sharpman76 again, and I got another command that you'll surely love.  It allows you to take anything but damaged tools/armor that contains metal, and smelt it down to get the iron or gold you so desperately desire.  As per the usual, most info is in the guide.

I've used tryashtar's 1.9 Command Compactor for all my commands.  Go check him out and give him some love!

To set up the custom command, run the command  "/give @p command_block".  Place it down, paste the command into it, then click the button that says "Needs Redstone" to make it say "Always Active".  Press "Done", and it should set up.  To get rid of the machine, make the outlier block that has a fill command in it "Always Active" .

If you have a bug or question, don't be afraid to leave a comment.  Telling me bugs helps me improve the command, and other people may also have your question.  If you like the command, feel free to leave a diamond.  Tell your friends about my profile so I can grow my following.  See ya!
