Had this idea for a long time now, might as well share
I supposed it should be called something along the lines of "Don'tkey" "Auchey" or something like that. Not even sure if it's possible to make it.

Looks like we had pretty similar ideas... I just want the record to show that I did not see your entry and then come up with my idea. I know I personally get frustrated if it looks like someone piggy backed off my ideas in competition things likes this, so I just wanted to clarify that that is not what happened. I came up with the idea a few weeks ago along with another cap that was going to look sorta like a bear trap and I was going to call them trap caps. So, yea... the similarities are purely coincidental and even more so because they're right next to each other.
edit:
I call this "Pins and Needles"
Similar to the tack idea posted above (swear I did not see it before I made mine), but it has an array of needles embedded into it like the magicians trick:

The purpose is to train and get magical fingers while typing.
After seeing this post, I realize that the idea of making caps that hurt, or are sharp or whatever, is a pretty common theme when thinking of "the worst cap ever," and not terribly unique which makes me feel better for not having posted mine first.
so carry on, i guess..
