The attentive can note that some model numbers are missing in the Del Tin line-up. Here follows a summary of the discontinued weapons I know of. Some of the weapons had three-digit product numbers, which I've allowed for by writing the old number (in italics) after the number they would have had if they had been around today. Numbers within brackets indicate unknown models. The list covers swords and daggers only.
