Got one like that and an army version with the regular shovel head.  Real metal and works when you need it.

I have been using an older version of this shovel for years.  https://www.blackdiamondequipment.com/en_US/product/deploy-shovel-1/

I have the Walmart version of this Clam shovel. Works great and I like how it telescopes out and back into a compact size.

That's the one I have, it's very nice imo.
