It is one of the largest, most beautiful and most sought after trick locks in our puzzle world. Majestically large and w...

This was my IPP design competition entry in 2006. It was my tribute to Nob Yoshigahara. I so love his Unhappy Adolescence puzzle based on the P pentomino+ 2x1x1 block, that I thought I would try a U pentomino +2x1x1 block and see what I could come up with. What I found was that 9 pieces plus a single cube would make a nice 4x4x4 puzzle. The puzzle consists of 4 pieces plus their mirror images and a self reflective piece plus the lone cube. Several problems can be dreamed up and attempted. T...

By lengthening the triangular stick segments of the Permuted Third Stellation, a puzzle that resembles a nest of triangular sticks results. At first glance one might expect to be able to simply pull one of them out thus collapsing the whole thing... not so easy! Comparing this puzzle to the Permuted Third Stellation, the additional length of the triangular stick segments eliminates one of the two solutions, and makes it so that the remaining unique solution is only able to dis...

T2 Popplock by Rainer Popp - you should know what this is. This lock is missing it's original packaging but comes complete with the usual manual/instructions.  To be honest I do not even know if Rainer was shipping his early locks in the same straw filled boxed. There are a few superficial marks  and a light patina on the puzzle which are visible upon close inspection, the photos and lighting make them more pronounced. They will disappear with a light polish/clean.   ************************...

This Stickman Mahogany Chest is one of the very first projects to bear the Stickman logo. It is hand crafted entirely from mahogany, with a lid crafted of mosaic of pieces so strongly interlocked that it can easily support my weight. In fact the entire thing is very sturdy. This is not really a puzzle as much as a large hope chest, with sliding knick knak tray and lots of drawers and compartments (some of them secret). For nostalgia the original sales leaflet is still taped under the lid, an...

This puzzle was made by Lee Krasnow. It is called the Cluster Buster but it is made in a truncated version and uses three different woods to make this puzzle which is an easier puzzle according to Lee because of the truncated end pieces of the puzzle. They make it easier to grab in order to take it apart as well as put back together. I find them both difficult but understand what Lee means when he says the flattened tips make it so that it does not require 6 fingers to take apart the non truncat...
