If i have to make the list
1. Duh human mind.
2. Sword (any type) Sword are pretty much a cultural universal.
If that is not specific enough for you then the Gladius.
3. MG34 German machine gun which is the template for most modern MGs
4. Long bow Revolutionized feudal combat.
6. Spear Mam's first constructed weapon. Dont take hand axe **** to me, it isnt constructed unless it has two seperate peices incorporated into one.
7. 1911a1. not the first semi-auto pistol but certanly the gold standard.
9. which ever mauser has the original mauser action..... Cant look it up at work
10. Tazer. Makeing combat less deadly for the 21st century.
These are all hand held/personal weapons list would be different if we include weapon system/ vehicles/nukes
Tell me what you think?
