I fixed our chewed pencils, but is there a cure?

One thing that I will never understand my children is the pencil-chewing habit.  Why?  Why?!

I never chewed pencils as a kid.  Never.  I chewed straws, but never pencils.

I so wanted to buy some nice, beautiful pencils to start this school year, but alas, there is no way my patience will be able to last if they chew some Ticonderogas.

The sight of these chewed-up pencils in my pencil jar was driving me crazy, so I asked Jeremy to cut off the tops with his mitre saw.

Much better.  I’m not sure if this will keep them from chewing on them, but at least, temporarily, my pencil jar will look nice again.

Do you have a cure for pencil chewers?  I think this might call for a visit to Mrs. Piggle Wiggle!
