Another reference from Gerber knives glossary> Tang: The portion of the blade where it connects to the handle. Full Tang means that the tang goes through the handle to the Pommel.
I do not own a Gerber for well one reason, they are Gerbers! To be honest it is a sales gimmick, they want buyers to believe they are getting a quality full tang knife but that little partial tang can not and will not hold up like a full tang knife, you have a true full tang with your 124LE, I wish you could see the tang on it right next to a 119 tang with no scales and you will see a huge difference.
