Uhhh... dude, lay off the pipe for a day or so. Anyway, to answer your question, one is significantly thicker than the other. I don't feel like checking, but I think that the Light is 1/8" thick. The LTC is 5/16" thick, and WAY heavier (weigh heavier? yea, that one's terrible; I know). The Light has the coated blade. The LTC is uncoated and has a much pointier tip. Thats is one bad knife! FORGET the Trailmaster; give me one of dem things!
