Making a tool come back to you?

So this is my Sword script and I don't want people to be able to press backspace to give their sword to other people. How would i do it and where would I place it in my script?. All help appreciated! Thanks!

r = game:service("RunService") 
ching = false
Tool = script.Parent
sword = Tool:WaitForChild("Handle")

function blow(hit) 
	if ching == true then
		return
	end 
	local humanoid = hit.Parent:findFirstChild("Human") 
	local vCharacter = Tool.Parent 
	local vPlayer = game.Players:playerFromCharacter(vCharacter) 
	local DD = vPlayer.DD 
	if humanoid then 
		ching = true 
		tagHumanoid(humanoid, vPlayer) 
		local damage = math.random(script.Parent.MinDmg.Value,script.Parent.MaxDmg.Value)+math.floor(vPlayer.leaderstats.Lvl.Value/5)
		DD.Value = DD.Value + math.floor(damage)
		humanoid:TakeDamage(damage) 
		local part = Instance.new("ScreenGui") 
		local part2 = Instance.new("TextLabel") 
		local c1 = script.FadeClean:Clone()
		local c2 = script.TextRiser:Clone()
		part2.FontSize = "Size18"
		part2.Size = UDim2.new(0,50,0,50) 
		part2.Position = UDim2.new(0.5,0,0.25,0) 
		part2.BackgroundTransparency = 1
		part2.Parent = part 
		c1.Parent = part2
		c1.Disabled = false
		c2.Parent = part2
		c2.Disabled = false
		part.Parent = vPlayer.PlayerGui 
		if (damage == 0) then 
			part2.TextColor3 = Color3.new(0/255,102/255,255/255) 
		else 
			part2.TextColor3 = Color3.new(255/255,255/255,255/255) 
		end 
		part2.Text = ""..damage.."" 
		wait(0.4)
		ching = false
		spawn(function()
			wait(.5)
			untagHumanoid(humanoid)
		end)
	end
end

function tagHumanoid(humanoid, player) 
	local creator_tag = Instance.new("ObjectValue") 
	creator_tag.Value = player 
	creator_tag.Name = "creator" 
	creator_tag.Parent = humanoid 
end 

function untagHumanoid(humanoid) 
	if humanoid then 
		for i, tag in pairs(humanoid:GetChildren()) do
			if tag.Name == "creator" and tag:IsA("ObjectValue") then
				tag:Destroy()
			end
		end
	end
end

function attack() 
	local anim = Instance.new("StringValue") 
	anim.Name = "toolanim" 
	anim.Value = "Slash" 
	anim.Parent = Tool 
end 

function lunge()
	local anim = Instance.new("StringValue") 
	anim.Name = "toolanim" 
	anim.Value = "Lunge" 
	anim.Parent = Tool
	local force = Instance.new("BodyVelocity") 
	force.velocity = Vector3.new(0,10,0) 
	force.Parent = Tool.Parent.Torso
	swordOut() 
	force:Destroy()
	swordUp()
end 

function swordUp() 
	Tool.GripForward = Vector3.new(-1,0,0) 
	Tool.GripRight = Vector3.new(0,1,0) 
	Tool.GripUp = Vector3.new(0,0,1) 
end 

function swordOut() 
	Tool.GripForward = Vector3.new(0,0,1) 
	Tool.GripRight = Vector3.new(0,-1,0) 
	Tool.GripUp = Vector3.new(-1,0,0) 
end

Tool.Enabled = true 

function onActivated() 
	if not Tool.Enabled then 
		return 
	end 
	Tool.Enabled = false 
	local character = Tool.Parent; 
	local humanoid = character:FindFirstChild("Humanoid")
	if not humanoid then 
		return 
	end
	attack()
	Tool.Enabled = true 
end

script.Parent.Activated:connect(onActivated)
connection = sword.Touched:connect(blow)
