I had one. After about two years the loop that holds the unit on the keyring broke.
Mine came with a decent edge. When using the bottle opener or the phillips screwdriver the serrated part of the blade requires a bit of attention. From other posts you made I know that you also have a decent FAK. That might come in handy wink.
I would not buy one again.
