Thanks for the excellent pass-around!
I have only one suggestion: 3 days instead of a week.
The Salsa pass around has taken forever to get around. (No offense, DaveH) It has lost its excitement.
You can easily figure out a knife in just a day or two - I'm sure every one of us will have it with us all day those first 2 days.

To really get to know a knife, you'd have to have it for a month or longer and have a few real chances to use it.
Plus, knowing they had a week caused some of the Salsa reviewers to put off writing about it, and one even forgot to mail it off on time - very frustruating for those waiting. If you can only have it for a few days, then you'll be sure to try your darndest to reivew it and pass it on.
How about this: 3-4 days to try it out, 3-4 days in the mail. Then it really only takes a week, total time.
Otherwise, it could easily be 3-4 months before it makes its way to calyth...and he might forget by then

...hmmmm....what's this?
