Customer video review of Viper Tec Jax OTF Automatic Knife – D2 Steel

I have several knives from viper-tech and this is one of my favorites. It’s sturdy and feels substantial in your hand. I don’t use the case that comes with them, but they have improved them also.

Viper Tec Jax OTF Automatic Knife – D2 Steel

I like all of my Viper Tec autos and I really like this one. It is well built, has good strong quick action. However, the big reason I love it is the size of it and its' light weight. It is a good 7.5" pocket knife, but what makes it so good is the overall weight of the knife. This may be the lightest Viper Tec knife I own and that is out of 60-70 VT knives.
