There was a thread about a year ago on rec.knives about the Warlord. Somebody was looking for one, and said they had been "withdrawn from the market". I asked what that meant, and the gist of the reply was that they served no sporting purpose (so to speak). The implication being they were considered too dangerous to fall into the hands of criminals.
Now, I'm pretty darn sure I saw one in Outdoor America in OKC some months before this. (This place is a huge CS dealer.) So I believe they existed, but I've haven't seen nor heard of one since.
When I hear people talking about a knife being "too dangerous", or a "criminal weapon of choice", I like to point out that most people in Rawanda were killed with simple machetes. And, for $5-$20 you can go into any Lowe's, hardware store, etc. and pick up one of these ruthless killing machines. You can even get brush axes or billhooks that are every bit as "dangerous" as the Warlord.
'Course, CS's sometimes over-the-top marketing probably wouldn't play very well in a lawsuit.
