SCHOTF8BS: OTF8BS OTF Viper Double Edge, Black Combo
Schrade
Schrade has so many models - but they are cleverly designed, well made and really economical. These Out-the-Front openers are super fast and well made. They have a safety on the side and the mechanism takes a little getting used to, but they are truly awesome and impressive. It's got a black coated 3.35" double combo edge spear point blade, tough aluminum handles, finger actuator, glass breaker, and a locking safety mechanism. This is a cool looking knife and one you get the hang of it, will be something you will enjoy playing with.
Pocket Clip
Includes a pocket clip for easy accessibility and a more secure carry.
AUS-8 Stainless Steel
Offering entry-level to mid-range performance, this Japanese-made stainless steel is easy to maintain and has a long history of high quality.
Aluminum Handles
A solid, lightweight material that can be molded, textured or anodized to provide better grip under extreme conditions.

Pros: Blade Material, Blade Sharpness, Ease of Opening, Lock Ease of Use, Lock Type, Overall Quality, Pocket Clip, Weight
Cons: None
Great Product; Care Required
I love it - and having owned it before, quickly remembered that maintenence is key. After a while of ejecting and retracting, you'll find it may stick or lock up.WD40. Good as new. Don't know if that's the suggested lubricant but has worked for me.Also, don't accidently catch the safety on your way in or out of your pocket. Happens.

Update. Don't like it.
I changed my review from 5 star to one. Due to the fact it quit opening and locking within one month of light EDC use. Shame. Because I really like this design. When I took it apart the slider bar was roughed and chipped up from the blade. And cut into the slider bar. Thereby ruining it's locking and full opening ability.Sorry I had to update my review from 5 star to one. If you buy it. I hope you get a good one.

Pros: Ease of Opening, Overall Quality
Cons: Pocket Clip
Good for the price.
For the price. I cannot complain. Mine works fine. No up down blade play and very little barely noticeable side to side blade play. After a few discharges it seemed to lock up better and break in smoothly. Plus it is legal in Virginia. And got a good cyberpunk/futuristic tacticool look.Pocket clip is a bit tight. No biggie.
