Spiral Burr is a six-piece burr of interlocking spirals. Next to sliding and rotation, spiraling is the third fundamental way of turning pieces in an interlocking puzzle. The spirals are notched. The object is putting the puzzle back together after turning it apart.

Here is a sample video of the puzzle. Note: this is the solution to the puzzle as well.
