I wanted to make a small point about one of the definitions listed in A Beginner's Glossary of Terms. This feature gives the following definition:

Point of Balance (PoB)
The Point of Balance on a sword is simply the point on which the center of gravity is located. In other words, it's the spot along the blade's length that has equal mass on either side of it. The PoB will vary widely between sword types and their intended functions.

The statement "it's the spot along the blade's length that has equal mass on either side of it." and the statement "the point on which the center of gravity is located". are not necessarily compatible. The problem is that a sword may have a center of gravity that is not the same as the spot along the blade that has equal mass on either side of it. The definition listed here only applies to swords that are symmetrical and strait. The center of gravity of a curved blade is rarely on the blade itself. Furthermore, the center of gravity of complex hilted weapons is also often askew from the centerline of the blade so equating the point of balance with the CoG is a bit misleading and missing the point, pun intended :) .

I think that the PoB is rightly defined as "the spot along the blade's length that has equal mass on either side of it." But center of gravity, or center of mass, needs to be defined separately as the point at which mass is evenly distributed.

Just a small point, but it makes a difference when thinking about and examining a weapon and its use. This distinction might come in even more handy when examining hafted weapons.
