From puzzle master Nobuyuki Yoshigahara: "The early 20th century witnessed a kind of puzzle boom, which in 1905 gave birth to an absurdly simple looking puzzle known as the 'Devil's Claws.' We were surprised at how nicely this new version turned out after deciding to revise the original. Don't let the smooth looks of this one fool you; you may become one of those who let frustration take over, and leave this puzzle forever unsolved. Dedicated to the true puzzler! The key word is 'claws'." Hanayama is known worldwide for challenging puzzles and quality manufacturing. Can you take the pieces apart, then put them back together again?
