I have two theories based on this, and with the help of numerous RPG formats:

1) "EQUIP" is based on the weight of the item when wielded by the user.

2) "WEIGHT" is how much it weighs when on the character's body, and a '+' reduces that weight when wielded by the user.

In this case, it says the weight is "150." Assuming that is in ounces, it means that the sword weighs around 9.4 pounds (rounded off). Which is double the average weight for a steel-based long sword. (Hence why I am assuming it is in ounces, due to the material.) But when wielded, the weight might feel like it is 105. which makes it feel like it has the weight resistance of 6.6. punds (also rounded off).

Again, these are theories. I prefer thinking that #2 is the logical choice, as he stated in the anime that the blade did have some weight to it. Which means that the metal used is both heavier and more durable that real world steel.

Hopefully this helps in some way.
