Dependable auto
Ryan M. on Jun 6, 2023

I bought this Hogue a couple years ago from BladeHQ and it’s been one of my most frequently carried EDCs ever since. Main reasons for this are: - highly satisfying action/really snappy auto - the blade stays sharp way longer than a lot of my other EDCs - it’s lightweight and dependable; I carry this when jogging/hiking and with any pants material - the discreet deep-carry pocket clip and overall size make it very easy to carry at work or anywhere else - the texture on the scales provides a solid grip in hand but doesn’t catch or rub on your pants pocket - It perfectly complements my Sig P365 Overall, highly recommend this auto.

Great Knife!

I bought this as my first Automatic knife and I can not say it disappointed me, the action is very snappy and powerful with a beautiful design the blade came razor sharp. If you do like Sig Sauer firearms you should like the handles on this knife they feel like the grips on a p320. I would recommend this knife if you are capable or curious about it, if you cant get the automatic variant I am certain the quality of the able lock variant is just as good. All of this stays true but as i used it and inspected it a part of the blade i realized was hitting the back of the handle when closed rolling the edge. I dont know if it was from wear or manufacturing issue or what but it is annoying.
