Kendachi Monosword Cane

The Kendachi Monosword Cane is a melee weapon hidden within a rich, synthetic mahogany-finished walking cane. Twist the handle to the left, and a lock will release the 55cm blade.

Note: This weapon will shatter with a 4 on 1d10 if fumbled or parrying. Otherwise it is consistent with all other rules governing monoweapons.
