Help! We found these while packing & have no idea what they are! Any ideas?

There are 8 of them. They are all black metal, cone shaped, thingies... one end is sharp. The small part screws into the bigger part, and the screw portion sticks out a long way as if it is meant to screw into something.

My step son loves animals and the macabre almost as much as I do, and he got me an absolutely amazing gift today!!!

Queso is a bit messy with the tube meat...

I had to go into the office for planning meetings, and didn't want to leave my girls all alone all day, so I brought them along so they can be lazy bums who sleep all day at the office instead of at home.

I tried really hard to get a picture of myself doing pullups today in hopes of showing off my tattoos, but it didn't work out well... I had to zoom in way too far, and that combined with the motion just resulted in this mess... ugh.
