Throwing issues on my Murder Mystery game, please help?

Hello! I am currently making a murder mystery game on Roblox and I am having issues with the throwing. Simply when I press E (the throw knife button) the throwing animation plays on every other part except the arm with the knife and the knife doesn't release or throw it just stays in the hand. I don't know what I am doing wrong, and that is why I am here. Please help! Code listed below:

-- Basic settings
local ALLOWED_DISTANCE = 8
local XP_PER_KILL = script.Parent.KillXP.Value

local tool = script.Parent
local debounce = false
local throwCooldown = false
local allowedToHit = false
local throwType = 0
local lastMouseHitPos = nil

local toolPlr
local animDraw = nil
local animStab = { nil, nil, nil }
local animThrow = nil

function enableEffects()

    -- Enable em
    for _, i in pairs(tool.Handle:GetChildren()) do
        if i.Name == "Effect" then
            i.Enabled = true
        end
    end

end

function disableEffects()

    -- Disable em
    for _, i in pairs(tool.Handle:GetChildren()) do
        if i.Name == "Effect" then
            i.Enabled = false
            i:Clear()
        end
    end

end

script.HitPlayer.OnServerEvent:connect(function(plr, hit)

    -- Make sure the hit is valid
    if hit == nil or hit.Parent == nil then
        return
    end

    -- Check if player (and not this player)
    if hit.Parent:FindFirstChild("Humanoid") and allowedToHit and plr == toolPlr then
