Here are some weapons that have NOT been used in LoL yet (and a list of the ones it already has)

Quick list of the weapons that have already been used in League of Legends:

Sword: Bow: Crossbow: Spear: Guns: Staff/club: Twinblades: Axe: Hammer: Knives: Mace: Blades: Other unique: (kama) (baton) (sickle) (rapier) (trident) (lance) (shuriken) (anchor/pickaxe) (chakram) (boomerang) (blowgun/darts) (chain) (gauntlets) (shovel) (halberd)

So what is left that haven't ever been used? Here are some things that come to mind (I admit beforehand that my main source of memories of weapons that are not in League of Legends come from Dark Souls and Smite).

• Scythe: while technically one of Karthus skins wears a scythe, it is just visual and he doesn't actually use it. Unlike Thanatos from Smite. http://i.imgur.com/tAMZRJg.png

• Whip: Tahm Kech and Thresh both have some similarities with the behavior of a whip, but they are not actually whips. Again, a Smite God comes to mind. In this case Bastet and her whip with several thongs. http://o.aolcdn.com/hss/storage/midas/4caf99199d4cac4d9cb2cc16b20e04b1/200065635/Bastet+Night+Prowler+Card.jpg

• Halberd: EDIT. HECARIM USES A HALBERD http://darksouls.wdfiles.com/local--files/halberds/giant-s-halberd-onhand-large.jpg

• Saw blades: whether they are circular or long like swords http://www.zombieplaygroundgame.com/kcstr/bat_sawblade001.jpg

• Sling: EDIT. FORGOT RENGAR USES A SLING http://pre11.deviantart.net/eaf9/th/pre/f/2014/208/f/2/_smite__xbalanque_xps_only____by_lezisell-d7rlf2k.png

• Fan blades: also used as shields. Hi Kitana http://i.imgur.com/4IMdqHu.jpg

• Greatbow: a huge YUGE bow that is nothing like attack speed ones, but a slow and damage-y/cc-ish weapon (I actually created a ranged tank Champion concept for this weapon) http://i.imgur.com/LJmQtuT.png

Any more ideas that come to your mind? Feel free to share them!

Gunblade/Bayonet: (this could be super cool that it would attack ranged or melee depending on the distance to the target. http://vignette1.wikia.nocookie.net/finalfantasy/images/a/a7/Dissidia-Revolver.png/revision/latest?cb=20110218050949
