  6. I agree with most of the other comments on this post.

    But 1446 looks like a puller of some sort. Gear puller, spring puller, or like the battery terminal puller shown in a previous post.

  7. Correct answers so far:

    1445. Cigar punch
    1446. Don't know exactly what this was for, but I agree that it appears to be some type of puller.

  8. My friend linked me to this site last night and now I can't get enough of it. Hahaha. It's simply fascinating.

    I knew the paver though... I worked road construction as a summer job this year. Haha.

  9. 1444 seems like it's designed to hook onto something in order to turn it or pry it. The length multiplies the torque applied on the handle so at nearly a foot long it tells me whatever it is must be difficult to move.

    From the look of the spring on the tool I assume it has a very high spring constant which would make that part difficult to move in itself, which would also support the idea that whatever to tool is for must be difficult to move.

    But I could be completely off track.

A sheet of paper is fastened by 2 vertical clips on the upper cylinder. Pen on end of arm goes up and down based on pressure differential within cylinder.
    1442.
