This is a bit of a funny question.
I had an idea for a character recently where they'd have a Greataxe/Dwarven Axe and a Longsword. However, the Longsword would be stowed inside the handle of the axe so it can be drawn only when need be. Perhaps two-weapon fighting where possible and practical to draw it out, or keep it sheathed when only making a single attack per turn. Really, this is entirely for thematic effect as it is incredibly impractical via mechanics.
While my GM may just handwave this and allow it, I still want to make sure that there is some rule-backing here, if any.
Are there rules/concepts/implications that one can stow a weapon *inside* another weapon? Is this something that can be found on other, currently existing weapons?
I thought about just "reskinning" this and, mechanically, having the sword's sheath be a separate thing, only draw it while the axe is out and consider myself without a sword when I am without my axe. But, considering the Combat Scabbard exists, this makes this kind of thing a bit sketchy.
Not too big of a deal overall, but just wanted a bit of help/advice for it.
You should look at the sword cane.
Hollow pommel?

...what, no Inception jokes yet?
I confess I was waiting for dirty jokes.
Hey, that's remind me, where is that thread about a succubus in a grapple, I haven't see it for days!?!
There's the Sharpened Combat Scabbard, which is a slashing weapon you can swing the sword around inside. Just fluff it to be axe-shaped.
I have a Samurai (Order of the Flame) who won't draw his swords against anything without a blade, so he goes around whacking things with his Wakizashis in their scabbards until then.
Yo dawg, I heard you like weapons...
Aw, you beat me to the "Pimp my Axe" reference!
