ºNot last shot yet, if you fail now you can carefully cut the heads off with a Dremel and then get the remainder out.I have taken all the ones out that were screwed up over the years with the very small visegrips. You can remove the slides and put them in the oven if you have to set at like 200º. That will work but risks fire due to fumes.

I learned all I need to know about life by killing smart people and eating their brains.
Eat right ,Exercise ,Stay fit, Die Anyway!
