@klew: It uses A-GPS by default, but can be set to always use 'real' GPS. It works really, really well in the middle of nowhere and you can feel like a living, breathing anachronism lying in a field in your dungarees, chewing on some straw and watching the stars through your science-ajiggy.

Shouldn't it be half a 45-degree angle? I've always been taught that ~22deg is best for honing at home, and 22.5 is both pretty easy to eyeball and not off by enough to ruin the edge.

@bmearns: They do, but it's $32.

@mrmysterious: I did say 'mistaken.'

I tend to extend my index finger and touch the inside of the recipient's wrist when I shake hands. It's unintentional, just happens — but it's been mistaken more than once as a Masonic/secret-society thing, which is a bit awkward.
