This is my lever box. It’s the first real puzzle box design I made, although it has been refined over the years. This particular one is made from solid birch ply with a burl veneer to the top face. The levers are made of bog oak. Bog oak is a lovely wood to work with, essentially it is an oak tree that at the end of its life has fallen into a bog and soaked for a 100 years or so. This process gives the bog oak a dark almost black colouring and a fine structure. To find out more about bog oak please look at my materials page.
