Jim,

Here's a story and picture for your extreme stories:

I have been tiling my bathroom and found that the fisher space pen was the only thing I could reliably use to mark the tiles for cutting. Magic marker and pencil lines instantly disappeared once the spray from the wetsaw hit the tile, losing my cut line. The ink from the space pen held on long enough to guide me through detailed cuts. Here's a picture taken a few days after the job, the tile mastik still firmly dried on the pen - pen still working, of course. I've since cleaned the pen and it's once again back in my wallet.

All the best,

Eric L.
