A Well built Tough Knife. It'll jump outta ya hand, So keep a good grip. Came Extremely Sharp, Still Sheep and it's my EDC. It Matches my P220. If you have a sig, you gotta have this. If you Don't, You gotta have this. And the American Flag print on the clip, Out ,Bleep'n, Standing! Under$200 For a American made knife built this good, Yea it's worth it. Bout 200 after taxes, But if your like me, won't compromise for nothing but the best, Well you just found one!

Best Auto EDC Knife?

Honestly, I love this knife. It's lightweight, durable, rugged. The auto mechanism works perfectly. The locking mechanism works perfectly as well. I am constantly fidgeting with this knife because of how well both of those work. The blade is super sharp. I can't say enough good things about this knife. Just go get it already! :)

Its a all around EDC knife and should give many years of use. Its also a automatic which for me is great easy to get it open when needed it does have a lock to keep it safe when not in use. Just a overall well made knife. Thanks to all!!

Great EDC Automatic Knife!

I first got this knife in the gray version same blade style. I liked that one so much I put this one on my wish list and bought one as soon as it was available. The weight, overall shape and ergonomics make this a great comfortable pocket carry, especially in a back pocket when I am carrying a pistol in the front pocket. Love the raised ribbed metal on the deep carry pocket clip which does help in drawing the knife from your pocket. Great overall quality, fit and finish. This knife and it's gray counterpart have become my go to carry when needing to use the back pocket. It's great for front pocket carry also but I have other knives I rotate for that use.

Bad handle, could be a great knife with changes

The blade is great. Flicking action is not that good but I can reverse flick it open. Locking mechanism is fine. The pocket clip rests upon gritty handle material making it a nuisance to stow and remove. The handle has good shape and sizing and I like the front choil allowing for different grips. However, the handle is slippery making the usage of the cross lock difficult and prone to making me drop the knife due to a lack of any friction. That's where it's really falling short. This smooth surface contributes also the difficulty of flicking action. Making changes on the handle and pocket clip in a generation 2 version could easily move it to 4 stars. To make 5,they need to improve the action on the blade. My other Hogue is 10 times better.
