Well, I was finally able to get all three tools closed after a lengthy process. I ended up having to get the shackler closed first (which took quite a toll on my hands, fortunately no blood loss
).
After closing the shackler I realized that I needed to open it to the 90 degree position (thanks for that suggestion or I probably wouldn't have gotten it). I then had to get the marlinespike to a 90 degree position as well to get the knife blade to move and eventually all 3 were able to be closed.
Thanks for the posts!
