Champ

Stave Puzzles of Norwich, VT has developed some of the most extraordinary techniques in cutting puzzles over the last 30 years, including Champ in the 1970's with color of pieces identical on both sides and with multiple double cut pieces. Thus, the puzzle can be assembled in many different dragon forms, but only when the dragon appears to be swallowing its tale (as in the puzzle displayed) has the assembler achieved the "correct" solution. This technique is called "double cutting-challenge" and while a staple of the Stave repertoire, is little used by other makers today.
