Greetings!

My MX500 handpiece went open in the handle. Does anybody know how to take it
apart?

You don't. You bite the bullet and buy a new one. There's a new one on eBay for $77 or you can go to Mouser for $104.25.

I use my Metcal quite a bit and am still on the same handpiece for 15 years but I do have a shiny new handpiece "just in case". Also, my Metcal was bought used on eBay.

Actually I just managed to take it apart. I applied compressed air to the
tip entrance and the guts popped out like a champagne cork.
