Can a Glaive be stowed in a Ruby Scabbard, as a Glaive is both Polearm and Heavy Blade?
I think RaW means it can, but it somehow feels "wrong" to put a polearm in a scabbard
Group: Heavy blade (Blades are balanced edged weapons. Heavy blades share some of the precision of light blades and some of the mass of axes. Heavy blades are used primarily for slashing cuts rather than stabs and thrusts.).
Polearm (Polearms are weapons mounted at the end of long hafts. All polearms also fall into another category of weapon, usually axe, heavy blade, or spear. Polearms are reach weapons.).
and the Ruby Scabbard ...
Property: This scabbard resizes to fit any light blade or heavy blade. You can draw a weapon from this scabbard as part of the same action used to make an attack with that weapon.
