Victorinox pocket pal

[RexRazorX]

If you like the pocket pal alox - this is another one to consider. You get a multi-tool instead of the small pen. I carry this one alot. It's so light you forget it is in your pocket - perfect for a suit or dress pants. It is 83mm closed.

These elinox versions, the predecessor to alox iirc, makes a Great knife to stick in a bifold wallet. They sit in the bottom unnoticed until the day you "forget" a knife, or can't carry one to an office or such.

For what it's worth, I find the plastic covered version friendlier in use. The "alox" version is a bit too thin for my taste.

The wonderful thing about here is the difference of opinion

This Secretary has been on my key-ring for years
the great thing about this knife is how thin it it
Very friendly for a key-ring
