Tortoise blade
Superior one-handed melee weapon
Cost: 10 gp
Damage: 1d6
Proficient: +2
Weight: 7 lb.
This bony or chitinous plate is affixed with a short blade that points forward from the wielder's hand. An enchanted tortoise blade can be used as a magic shield or a magic weapon, but not both. When enchanted as a magic weapon, it does not occupy a character's arms slot. A tortoise blade and a spiked shield are considered to be the same weapon.
Properties:
Off-Hand (An off-hand weapon is light enough that you can hold it and attack effectively with it while holding a weapon in your main hand. You can't attack with both weapons in the same turn, unless you have a power that lets you do so, but you can attack with either weapon.).
Group:
Light blade (Light blades reward accuracy as much as force. Pinpoint attacks, lunges, and agile defenses are the strong points of these weapons.).
