Kelly's Korner - Can you name these kitchen gadgets?

 

Hey, All,

We were moving my mom last week and I was going through the kitchen drawers and found some old gadgets that I thought were really interesting.  Two I knew what they were, but I am appealing to you all to help me identify the third.

The first one is this:  Hint - It will help make some great pies. 

The second is this:  Hint - For the weak of wrist.

Now this is the mystery gadget:  I have not a clue as to what this "knife" is used for and, so far, neither has anyone else I've shown it to.  If you know what it is, please let me know.

 
 
 
 
 
 
  I love kitchen gadgets of all kinds so if you have some old, unusual, or mystery gadgets, please send me a picture and I'll share it.

Have a great week!
