Marking

Moving a pair of old beds (1930?) with my car, I was surprised to see a succession of 3 chisel marks on the wood. A pneumatic chisel gone wild? Looking further I could see that the 8 joints were paired with roman numerals from I to VIII, a nice idea.



Looking at the joints I see nails with a X section used to pin the joint. I see two advantages to these pin-nails: On soft wood there is no need to drill a hole, and the lengthened section of the nail avoids that it can be pulled through the wood or easily bent.
