I recently picked up a used SAK Fieldmaster and was happy as a clam that the guy knocked off $8 because it was missing the tweezers and toothpick (also had a broken scissor spring). I still figured that the parts shouldn't cost that much. My questions are is where is the cheapest place to get these parts from. Victorinox prices were ok, but they wanted more in shipping than the parts cost. My main two questions are am I correct that I could put a pen in place of the tooth pick and is the pen any good? I know it won't work as well as a regular pen, but I don't see getting much use out of the toothpick.
