Sword with handle found on Mars near Curiosity Rover, May 2016, UFO Sighting News.

Date of discovery: May 2016
Location of discovery: Mars
Source photo: Unknown

This was submitted to us by a reader this week. A sword was found on Mars near the Curiosity rover. This is cool, because it shows great detail and the fact that its mostly intact. The hand is curved like we would expect it to be. One edge of the sword is straight. The tip is bent at a straight angle and the bottom of the bad seems to have been damaged with indents of it, probably from some battle long ago. Excellent discovery and thank you for sending it into USD.

This appears to be a knife with a handle. The area in the upper right of the photo appears to be manipulated somehow.
