Modular weapons are possible yes. I've seen it in Pathfinder errata. but it's like an extra 1K for the weapon to make it that way and it's easier to break. (due to the engineered weakparts wehre it has to collapse/fold at)<br/><br/>and yeah I just wanted to stow the weapon itself. since a spear, while useful as a weapon and walking stick tends to poke you wrong if you sit down with it XD
