Wellcome to the forum

Few years ago, when I found this forum, I couldnt tell the difference between a kitchen knife and a rapier!
Now i think i know some things (thanx everybody!) and i still learn.
The khyber knife is the far left sword. This one is huge. Normally they are about 15 inches long. The name "khyber" comes from "Khyber Pass" that is between Pakistan and Afghanistan. If you search old threads of the forum (from the first page, 2000-2004) you will find more information about it.
