A 6 piece board burr in the shape of “shaking hands” with two closed loop pieces. Level 14.4.2, feels a little harder due to the confusing nature of the moves, but this would not be classified as a difficult burr by most. I was able to disassemble it by hand, but used BurrTools for the reassembly.

This puzzle uses 5 fat "Logs" and 5 thin "Sticks", some joined so there are 7 pieces total. John Devost has added decorative ends and a spiral groove to the logs to create a unique look for this puzzle. The sticks are not glued in place, but held with what appear to be brass pins. Disassembly is easy, assembly is the tricky part, although I think this is one of the easiest of Coffin's "Log's and Sticks" type puzzles.
