Issue with functions and tools. Kills on touch even though it must be activated?

I have a knife script that works. There's a small problem. When I equip it, the .touched event complete ignore .activated event. This is probably a simple fix, but I don't know how.

EDIT:

I FOUND A SOLUTION. sorry for wasting your time

CODE:

local tf = false

script.Parent.Parent.Equipped:Connect(function()

        script.Parent.Parent.Activated:Connect(function()

                if tf == false then

                    tf = true


                    local anim = script.Parent.Parent.Parent.Humanoid:LoadAnimation(script.Animation)


                    anim:Play()

                        script.Parent.Touched:Connect(function(part)

                            part.Parent:BreakJoints()

                        end)

                    wait(1.5)

                    tf = false

                end     
        end)
end)
