The world’s first all-metal, smash-proof guitar

"We had to design a guitar that is unsmashable in all the different ways you can smash a guitar,” Loikkanen said. “The engineering challenge was that critical joint between the neck and the body that usually cracks on a guitar.” So Sandvik Coromant engineers decided to eliminate the joint. Both the neck and fretboard extend into a rectangular “hub” that reaches deep into the guitar’s body." See how it was done and listen to its sound !
