Here's an idea~

Katana
http://vignette2.wikia.nocookie.net/fallout/images/e/e9/Katana.png/revision/latest?cb=20110927225512

Damage: 68
Uses: 200
Craft: 20 Flint (for the blade), 1 Walrus Tusk (for the handle) & 1 rope (to hold it all together)

Custom Effect: When the player attacks something with the katana there's a 25% chance they'll do 25% more damage & spawn that effect the whip does on stuff, maybe it can also shake the screen a little. Basically a critical hit.

OR a 5% chance to instant kill any entity (excluding players & bosses)

Picture : Maybe just change colour of Ham bat enough
Weapon Name : Monster's Ham Bat
Damage : Same as normal Ham Bat
Uses : Same as normal Ham Bat
Craft : 10 monster meat
Custom Effects : 20% chance stun monster for 3 sec or 10% chance make the monster become alliance for 10~15 sec

Picture: the throwing knife
Poisoned knife
Damage: 60 with 15 or 30damage/sec DoT(Damage over Time)
uses:150 /300/500 or infinite (maybe we put this configurable)
Craft:the same with 5 monsters meat added
Effect: The poisoned knife has a little green light aura
Has high attack speed
Adds 10% move speed and give 10% more resist to damage to players characters
Sorry for my bad english i have posted another idea in the same mods but for "Don't Starve"
Maybe you can put it in DsT too.

Do you want it to be throwable but not needed to be picked up? Since you referring to attack speed

If it is not needed to be picked up then this damage is kind of too high. I will add it with some changes
P.S. tomorrow 2 items will be added and i will start working on it.

ok so do what you want for the damage and yes please make it throwable and no need to picked again cause i have this mods and i'm using the throwing knife but one day the attacks miss and my knife dissapears TwT(for the damage over time put smething like 2damage per sec for 5sec or 10sec)

Quick idea based on a new reign patch:

Picture : A variation of fire/ice staff with thulecite holding.
Weapon Name : The Lazy Magician
Damage : 81
Uses : 200
Craft : 5 Thulecite, 1 Irisdecent Gem, 5 Living Log, crafted at Fully Repaired Ancient Pseudoscience Station
Custom Effect : Projectile, ranged end-game weapon, 33% chance to freeze target, 33% chance to put it on fire, 33% chance to struck it with lightning (we simply can't decide coz we're too lazy :) ). Can be repaired with right-clicking Thulecite into the weapon. Each thulecite repairs 50 uses. Does not break when durability reach 0.

The two swords might be a nice feature because i like the way they look and for now the only sword is anime so i have a hard time finding it
