I have recently been buying some wooden puzzles from various sources. As both a fan of wooden puzzles, and a reseller, there are many manufacturers that unfortunately just aren’t worth much money in the marketplace. As a result, I often pass on buying a puzzle if it is not something I personally would be interested in or have a market for. I really focus on about 5 or 6 manufacturers for my core business. Recently, I have had the opportunity to acquire some puzzles as part of a lot that I ordinarily would not have purchased. One thing that I have noticed is the the wide variety of cutting styles that different manufacturers use (or used if we are talking vintage puzzles). Some are the traditional puzzles with the knobs that interlock, others are cut almost as if they were in a hurry with very straight lines and almost a grid like pattern. Most likely they were in a hurry as puzzle cutters in the early part of last century often had daily quotas of pieces cut per day, thus my hunch as to why they were straight cuts. Surprisingly these have turned out to the be the most difficult ones to solve. I have found that often you aren’t 100% sure you have the piece in the right place until you have quite a few surrounding pieces also solved. While I don?t foresee doing a lot of these in the future, it is interesting to see the many styles of wood puzzle cutting, and then researching why a manufacturer may have selected a certain style of cutting.
