How do i fix the wield of a tool?

I recently wanted to add some swords to my game and i have come across this issue:

https://gyazo.com/e52392c16e4aed4f8f2dd5f863ac945d

Do i have to just change the rotation of the tool?

Here's my current sword script:

r = game:service("RunService")


local damage = 7


local slash_damage = 12
local lunge_damage = 31

sword = script.Parent.Handle
Tool = script.Parent


local SlashSound = Instance.new("Sound")
SlashSound.SoundId = "rbxasset://sounds\\swordslash.wav"
SlashSound.Parent = sword
SlashSound.Volume = .7

local LungeSound = Instance.new("Sound")
LungeSound.SoundId = "rbxasset://sounds\\swordlunge.wav"
LungeSound.Parent = sword
LungeSound.Volume = .6

local UnsheathSound = Instance.new("Sound")
UnsheathSound.SoundId = "rbxasset://sounds\\unsheath.wav"
UnsheathSound.Parent = sword
UnsheathSound.Volume = 1


function blow(hit)
    if (hit.Parent == nil) then return end 

    local humanoid = hit.Parent:findFirstChild("Humanoid")
    local vCharacter = Tool.Parent
    local vPlayer = game.Players:playerFromCharacter(vCharacter)
    local hum = vCharacter:findFirstChild("Humanoid") 
    if humanoid and humanoid ~= hum and hum then
        -- final check, make sure sword is in-hand
        local guygettingsliced = game.Players:GetPlayerFromCharacter(hit.Parent) --OH LOOK, here's an edit 
        local right_arm = vCharacter:FindFirstChild("Right Arm")
        if (right_arm) then
            local joint = right_arm:FindFirstChild("RightGrip")
            if (joint and (joint.Part0 == sword or joint.Part1 == sword)) then
                if guygettingsliced then --If he's a player 
                    --if vPlayer.TeamColor ~= guygettingsliced.TeamColor then  
                        tagHumanoid(humanoid, vPlayer)
                        humanoid:TakeDamage(damage)
                        wait(1)
                        untagHumanoid(humanoid)

                end 
            end
            if (right_arm ~= nil) then
            local joint = right_arm:FindFirstChild("RightGrip")
            if (joint ~= nil and (joint.Part0 == sword or joint.Part1 == sword)) then
                tagHumanoid(humanoid, vPlayer)
                if game.Players:FindFirstChild(hit.Parent.Name) then
                    local Victim = game.Players:GetPlayerFromCharacter(hit.Parent)

                    end
                end
