Pictured below is a Ka-Bar Last Ditch Knife, otherwise known as the LDK.
Since receiving this one I've bought 3 more to give away to friends. I also got one for my mother, who absolutely *had* to have one upon seeing it.
I've seen some criticisms of this knife. Some say it's too small to do any damage. I tend to think it's better than nothing, hence the name "Last Ditch Knife." The one valid criticism I've read is that it's too small to hold easily. I could see how this wouldn't work for someone with big / thick fingers. My lanky digits have no issues with it.
Sorry for the poor picture quality. These were taken in bad lighting with a now outdated iPhone 3G. I'm amazed at how much better the pictures are on the new Droids.
If you're looking for anything Ka-Bar I highly recommend Tomar's Kabars. They've got just about everything, including some very nice USMC fighting knives.
*Had to drop by the parents place to grab a few things. That meant internet access and a new post for all 3 of my readers. ;)
