not sure, doing research now....

There's a really good chance too that the one on the Pfaff has its little hook bent. That's how mine was when I got it. I also had a Quilt Expression 4 on my bench that the owner used the threader once and it stopped working. The hook had broken right off. They're very fragile and sensitive to the wrong needle size and the wrong needle position. That's why I like the removable ones better.

Here are some new little goodies:

The top one is a Standard screwdriver, some of the rest appear to be clamps but are they for quilting maybe? The one in the center is a screwdriver with a broken out needle eye? I have no ideas for that one.

The black handled one looks like a tool for hooked rugs.

The ones on the left are hem markers. Fold the fabric up to the right mark and pin before sewing. I use them at work. The black handled screwdriver thingy is indeed for punch hooking. The yellow rings look like old ring cutters for opening packages.

Mrs. SewNSew

I wondered if the yellow rings were used as thread cutters? I have a latch hook tool but mine has a tab that closes so I thought this might be something different. Maybe it's an earlier type?

Thank you on the hem measures. Those could come in handy now that I know what they are!

The black handled thing looks to me like a tire plug tool. It works very similar to a latch hook tool but has a pointed end. The blade just under it is half a set of thread nippers.

The rest,

Mrs. SewNSew

Thank you Joe. I double checked and you nailed it on the tire repair tool.
