As this report says:

Designed for “college students, high school students, concerned parents, and commuters”, I’d seriously consider moving to a better neighbourhood if buying this kevlar re-inforced backpack, capable of stopping a .44 Magnum bullet, seems like a sound investment.

The manufacturer reminds us that “It’s a major survival advantage versus not having any protection at all and being shot with a couple of 9 mm/44 Magnum rounds.” – Somehow that’s never been particularly high on my list of criteria when I go backpack shopping – until now.

Having started a new position at a new (to me) school, I quickly discovered the dress code for the male executives was formal. This didn’t bother me, as I had been wearing shirt and tie at my previous school for a number of years. But it did get me thinking, that I should probably learn some more ways to tie a tie. Of course a quick search got me the results I needed. After all, I didn’t want instructions like these.

ScoutDB.org has a site, though it’s not overly pretty.

Then there’s the Tie-a-tie.net site which has good, clear pictures and instructions:

• Windsor knot
• Half-Windsor knot
• Four in Hand knot
• Pratt knot

Then, there’s also the video download sites. Now I haven’t downloaded these (you do need to purchase them), but they do have a clear picture of what the knot should look like when finished:

• Windsor knot
• Half-Windsor knot
• Four in Hand knot
• Pratt (or Shelby) knot
