How to destroy the tool after it touches a part

I wanted it so that the knife touches one of those black parts and you fall down and then the knife is destroyed and you don’t have it no more. Is there any way i can make it so that the knife is destroyed after one of the black parts is touched.

Here is the code for the black parts:

	local knife = game.StarterPack["Throwing Knife"]:Clone()
	local realknife = game.StarterPack["Throwing Knife"]
	local Fall = game.Workspace.FallOff
	if hit.Parent:FindFirstChild("Humanoid") then
		Fall.Transparency = 0.4
		Fall.CanTouch = false
		Fall.CanCollide = false
		wait(2)
		Fall.Transparency = 0
		Fall.CanTouch = true
		Fall.CanCollide = true
	end
end

script.Parent.Touched:Connect(U)
#2 
local tool = script.Parent
local handle = tool.Handle

handle.Touched:Connect(function(hit)
	if hit.Name == "Part" then --Change name if necessary.
		tool:Destroy()
	end
end)

Tool instances don’t have a “.Touched” event but as their primary “Handle” instances are BasePart instances they have a “.Touched” event.

Should the "Part" be named the part its gonna hit [ aka the black part ] ?

Yes, whatever part the tool’s handle ends up touching.

Well i tried using this script, there were no errors but the tool was still there.

	local knife = game.StarterPack["Throwing Knife"]:Clone()
	local realknife = game.StarterPack["Throwing Knife"]
	local Fall = game.Workspace.FallOff
	if hit.Parent:FindFirstChild("Humanoid") then
		wait(0.5)
		Fall.Transparency = 0.4
		Fall.CanTouch = false
		Fall.CanCollide = false
		wait(2)
		Fall.Transparency = 0
		Fall.CanTouch = true
		Fall.CanCollide = true
		local handle = realknife.Handle

		handle.Touched:Connect(function(hitted)
			if hitted.Name == "target4" then --Change name if necessary.
				realknife:Destroy()
			end
		end)
	end
end

script.Parent.Touched:Connect(U)
