I would challenge you to open mine. It is made harder when one has a halyard one with the bar in it as one cannot bend the legs in . The only shackle I have with captive pin is on the spinnaker halyard. It is a heavy duty one.I my experience captive-pin shackles can be opened without mechanical assistance if the correct technique is used.
My filler caps can be opened by flicking up the centre & using ones hands.
