How do I code a sword without using Touched event?

I have got a super easy way to code swords and it doesnt take much effort

so step number 1 is to insert a on touch damage script into the blade. The script should look lie this:

function onTouched(hit)
        local human = hit.Parent:findFirstChild("Humanoid")
        if (human ~= nil) then
                human.Health = human.Health - 50
        end
end
script.Parent.Touched:connect(onTouched)

and set the script to disabled

now,you want to insert 2 sounds into the tool, a equip sound and a knife slash sound. then just insert a normal script into the tool and type in this

script.Parent.Equipped:connect(function()
	script.Parent.Knife_Equip:Play()
end)


script.Parent.Activated:connect(function()
	script.Parent.Blade["Damage Script"].Disabled = false
	script.Parent.Knife_Slash:Play()
	script.Parent.GripForward = Vector3.new(0,5,- 1)
end)
script.Parent.Deactivated:connect(function()
	script.Parent.Blade["Damage Script"].Disabled = true
	script.Parent.GripForward = Vector3.new(0,0,- 1)

end)

then insert another normal script into the tool and this script will be for welding so type in this:

function weld()
	local parts,last = {}
	local function scan(parent)
		for _,v in pairs(parent:GetChildren()) do
			if (v:IsA("BasePart")) then
				if (last) then
					local w = Instance.new("Weld")
					w.Name = ("%s_Weld"):format(v.Name)
					w.Part0,w.Part1 = last,v
					w.C0 = last.CFrame:inverse()
					w.C1 = v.CFrame:inverse()
					w.Parent = last
				end
				last = v
				table.insert(parts,v)
			end
			scan(v)
		end
	end
	scan(script.Parent)
	for _,v in pairs(parts) do
		v.Anchored = false
	end
end

weld()
script:Remove()

I hope this answer helped! :3
