The Burgh Lock is 3D-printed from Shapeways in nylon plastic and dyed and assembled at MFAVE. It is a challenging lock designed by Splinter J. Spierenburgh. The objective is to open (and close) this trick-lock using only gentle force and the two different keys supplied. There are two keyholes - one front and one in back... A delightful challenge with a wonderful solution!
