Devil's Fist is a traditional Finnish puzzle typically crafted from wood, consisting of 6 intricately connected pieces. The objective is to assemble it as depicted in the accompanying image. The puzzle itself is not excessively challenging, yet it can take time and effort to solve. Perhaps its nickname stems from the frustration that arises when struggling to complete it, prompting one to throw their fist in the air, cursing the devil.
