Sharp Reminder

How appropriate is it to have magnets that look like kitchen knives sticking into your refrigerator? Very much so, I'd say, as things could get ugly in the morning if I forget to buy more coffee. Get them for $9.99 each at Think Geek, although they're sold out at the moment. The Geeks estimate that these rhodium-coated plastic magnets will be back in stock on the 24th of August, so check back then. Wouldn't it be nice to have a knife magnet so you can stick a reminder on your fridge to do so?
