I recently discovered that there are actually two different versions of the Utili-Key. One is the "6-in-1" version, with a knife blade. The other is the "8-in-1" version with a nail file instead. I had the 6-in-1 a while back. I considered it very useful as a backup tool, but I didn't like the position of the blade. When it broke, I didn't bother to replace it for this reason. Now that I have discovered the 8-in-1, I plan to carry with my Victorinox Executive, since it can supply a bottle opener and phillips screwdriver while adding very little weight.
I'll let everyone know how this different version works out once it arrives.
