Ive had my para military for around 36 hours now and i have been playing with it a lot, ive probably opened and closed it as many times as i would in 2 normal weeks but no real cutting. i just noticed the main pivot? screw is starting to come loose and causing side to side blade play. i tightened it and its fine but i cant see how it wont loosen again shortly if i dont do something. so do i use some locktite or is this normal or what can i do? thanks
