Rumors circulated for years about a possible Benchmade OTF knife. Good news Benchmade lovers- the knife has finally arrived. The Infidel OTF is, to put it mildly, awesome. We had some Benchmade reps in our store awhile back and I got to play with a Prototype. It was outstanding in terms of quality, action, and lock-up. D2 tool steel double edged blade, double ground. Anodized T6 aluminum handle. And a pocket clip for easy carry. This model features a BK1 black coated blade!

Blade HQ's Benchmade Infidel Review: ahhh yeah! A few features we really like is the sliding button on the face of the handle, instead of on the side as many others have. The milled "stepped" handle design assures that this knife will not be slipping out of your hand.

Great OTF
John B.
Fits my hands perfectly. Love the smooth deployment/action and the blade length. Deceivingly sharp even though Iím not a fan of the single bevel. Not sure why Benchmade chose this grind. I also bought an Ultratech. The Microtech has slightly less blade play than the Infidel. Both are acceptable. No complaints about the Infidel other than the cost. Itís a keeper.
Love it

I love this knife. Best otf I have owned.
Fun with limited practicality.
Michael D.
I love this knife. The dual action is a hoot, and it's built solid. The dagger blade has limited practicality as an EDC, but I knew that going in. I would recommend the satin version though as the black coating gets scratched very easily. The cool factor just can't be beat though.
Great OTF knife

I really like this knife. Iíve not yet got a Benchmade that disappointed me.
Great great knife all around

I have tried several different otf's in the last couple months I went through at least 3 or 4 before I found the one. And it is definitely the infidel a little costly but well worth it !!! There double edge d2 blade is sharp as a razor the action in and out is spectacular I'd recommend it to anyone looking for a great knife!! Thank u benchmade and blade hq.

Bought this one and the green infidel. Both are good, but the springs can wear out which they did on both of my models.

Don't deploy your knife without it fully extended! If you deploy it and the blade is free floating it wears out the springs in my opinion. That seemed to be the issue of why they'd wear out but benchmade's warranty fixes the knives so it's not the end of the world.
