You are starting another nice collection. There are famous spears and javelins to gather (if anyone makes them). You should have a Roman Pilum. And a Macedonian Sarissa (you need a long corridor to mount it, it is 6m long). And a Greek Hoplite spear of course. The Zulu spear (iKwla) is always mounted with the cow-skin shield and the Iwisa. In between you have pikes, lances, halberds etc. If knives are the archetype tool, spears are the archetype weapon. Bayonets on rifles are their residual descendants. But one needs o BIG house to keep even a modest collection.
I do not plan on collecting spears. I just wanted a few for decoration...can you tell I am not married.
Just wear a helmet, you'll be fine
I bet your courier was somewhat perplexed when a six foot long spear shaped package showed up on his truck!Def
