Reducing the number of weapon skills

[Anders]

Have you mucked about with redefining the weapon skills in GURPS? Here's what I've done:

All the Fencing skills are reduced to one skill: Fencing. Defaults to Knife and Sword at -4.
Broadsword, Shortsword, Jitte/Sai, and Two-Handed Sword reduced to the Sword skill. Defaults to Knife at -4 and Fencing at -4.
Knife defaults to Sword and Knife at -4.
Two-Handed Axe/Mace and Axe/Mace is one skill, called Axe/Mace. Defaults to Flail-4 and Polearm -4.
Two-Handed Flail and Flail is one skill. Defaults to Axe/Mace and Whip at -4.
Spear and Staff is one skill, called Pole. Defaults to Polearm at -4.
Polearm defaults to Axe/Mace and Pole at -4 but is otherwise unchanged.
Whip and Kusari are collapsed into the Whip skill. Defaults to Flail at -4.

Opinions?
