The TL-29 is a popular pocket knife pattern that is usually associated with WWII.  They are plentiful and fun to collect in that several different manufacturers made them (Ulster, Camillus, Schrade, etc.) and a great amount of variations exist (handle materials, shields, stamps, etc.).  The TL-29 knife has its origins in World War One (WWI), originally called the Signal Corp knife.  These were a bit smaller than the ones that were produced during WWII and beyond and were often made by Empire Knife Co and Schrade Cut Co.  The TL-29 features two blades, most commonly a spear point blade with a nail nick pull and another blade with a wire scraper and screw driver tip.  The screw driver blade commonly has a liner lock for additional sturdiness.
