Extremely lightweight, the Spec Elite Auto features a hard anodized machined aluminum handle that provides sensational feel and balance. The Spec Elite Auto is an automatic knife intended for military and law enforcement. It can be carried conveniently with its reversible low-carry pocket clip.

Customer Ratings & Reviews

Spec Elite I Auto is rated 4.875 out of 5 by 8.
Rated 5 out of 5 by from Perfect I bought this knife after battling back and forth between various Benchmade models. I just couldn't make up my mind but the moment I saw this knife I decided to pull the trigger. Granted it's not easy spending $100+ on a knife. The knife is lightweight, has a solid construction then you combine those with the sharp blade and full auto mechanism, it's a no brainer. In my line of work it's extremely important that I have a knife that can be manipulated with one hand just in case I need it. The knife could have been bigger but frankly I'll take functionality over size any day. This knife will go where I go.

Rated 5 out of 5 by from sad I had this knife and it was the best knife I ever had. I lost it on a foot chase in the woods. I had done everything to find it including a metal detector but no like. Maybe one day the wife will let me send the money again.

Rated 5 out of 5 by from Only Had this knife for a few weeks now and it is among my EDC. It replaces another SOG "assisted opening" knife that I carried in the same place. I also carry a Kershaw partial serrated in a shirt pocket for easy access and a Gerber Crucial Tool for those times I need more than just a blade. This site asks "Why do you recommend this knife?" My response is the old, philosophical one of "Why not?"

Rated 5 out of 5 by from Great EDC lite and ready for duty Bought this knife a month ago, at first had trouble with the knife sticking to my pocket when being retrieved from my pocket using the clip. Took the edge off the S and G in SOG, now slides in and out like butter. Good sharp blade, and strong spring. My favorite now, don't need to carry anything else.

Rated 4 out of 5 by from Solid Great knife and very solid especially being automatic knife. I only had a problem with it opening in my pocket. You can lock it but it is a hassle.

Rated 5 out of 5 by from Great EDC Have had this knife for about 3 months now. Wanted an average sized EDC auto. Have not been disappointed in the performance of this knife. Opens easily and love the lock. Holds a razor edge very well...just strop from time to time to keep it hair popping sharp. Highly recommend.

Rated 5 out of 5 by from excellent knife I bought this knife last week and I love it it fits perfect on my pocket and because of the design it doesn't matter what pocket you put it in it still works the same

Rated 5 out of 5 by from Fast, versitile, and law enforcement worthy I purchased approximately 3 months ago and cannot get over how well thought out the engineering is. Fits well in hand, very tactical, and clip ensures it will not slip out of your pocket. This is a great knife for the money and well worth the investment for law enforcement professionals and/or military.

    SOG Unconditional Pocket Clip Warranty

    Pocket clips can be broken if they are accidentally caught on foreign objects while wearing. To help prevent such occurrences, SOG recommends that you wear your knife in your front pocket, with the knife inside your pocket. If, for whatever reason, your clip bends or breaks and you would like to receive a replacement, fill out the Clip Request Form, or email/call SOG's warranty department. Damage to a knife handle because a clip has snagged is not considered "normal," and any such damage will be assessed under warranty. Learn more about replacing pocket clips in Knife & Tool Care.
