I am just watching the latest Cold Steel video, SOLID PROOF. For anyone who has never seen one of these videos (this is the third one, the first was PROOF, then MORE PROOF) they are pretty cool.
Cold Steel has been often touted as one of the biggest mall ninja companies in the world, but I like them because while they may be over the top, they are still believeable (no testing against Comm Bloc body armor or specially designed grooves to control blood spray

) and all in all it's a good product at a reasonable price. And the videos are pretty cool to watch too, even if you don't feel compelled to buy any of them!
You can order the DVDs free from Cold Steel if you are in the US, but if you can't wait that long or are in another part of the world, check them out on Youtube:
