The tortoise blade grants a +1 shield bonus to AC -- when you attack with it, you do not gain the shield bonus. The tortoise blade also provides a -1 Armor Check Penalty and a 5% Arcane Spell Failure chance. Like a spiked shield, the enchantments for the shield part and the weapon part of a gnome tortoise blade are done seperately.
Gnomes develop the weapon and train in its use for tight warrens where swinging a weapon is difficult.
