Naihanchi Real Karate Street Fighting Defense DVD

Excellent product. I love the security of having my Sharpshooter Keychain with me wherever I go. It's so simple yet has so much potential as a defensive tool. It's hard to imagine how devastating this thing can be until you hold it in your hand and practice with it. Even seeing the videos didn't do it justice for me; I had to see it for myself. Get one; you won't regret it. And you'll be safer for it.

Sharpshooter keychain was easy to use as it comes with 2 instructional dvds. Price was reasonable as well, overall it's worth buying.

These keys are super--they're tough steel, and they're weighted just fine (four on a Viper is all you really need); they're shiny, unscratched...perfect for any version of the Sharpshooter (I've tried them on the Viper and on the Titano); also, the shipping time is excellent. All of the products are top-notch, and so is the seller. I intend to buy more products, as I've never felt safer out on the streets than I have with my Viper. We are very grateful, Master Moran. Thank you. Sincerely, Michael~

Compact and very effective. I went to a locksmith and for free picked up some heavy brass keys that were damaged to put on the ring, I only have two keys. I have both the newest larger one and the small older model. For ease of carry I find the smaller one best.
