Heh, the XL Espada only fits into the pocket on two pairs of pants that I own, and is not useful for any pocket-knife type tasks.
The XL Voyager is just about in the same territory ...
I find that once a knife has more than a 4" blade, it becomes less useful for ordinary, "around the town" type of pocket-knife tasks. Up to 4" and I can use it for all my normal knife needs.
Plus, no one has ever gotten weirded out by my use of a knife in that size range, even at university.
If I pulled out the Espada XL to open an envelope in public, then yes, I'd look like a dork...probably a dork the cops would soon be conversing with.
