A "Loaded" handle?

[Happy Face]

Someone linked me to this video:

During the video, just after 1:15 in to the video, he says the knife is "loaded" with something. What does that mean, and what is it "loaded" with? I heard "shot" but I have no idea.

lead shot, for extra handle mass.

Haha wow.

I've heard of chef's knives that use sand, and can be fine tuned by the chef by pouring out or adding sand.

that is pretty cool.
