Question: I can't take the knife out of the case? Any idea as why?
Document: I was pretty excited to receive this SOG/Brous collaboration. It's a solid little knife, thick piece of steel and feels like it could take a beating. The sheath has good retention and easily clips onto your belt. The included clip only supports horizontal carry -- maybe a small teklok would provide other options (although I'm not sure about that).Despite liking the knife, I just can't get used to it.
I don't own a lot of knives or know intricacies of specialty knives, but I do have common sense when it comes to quality and garbage. This is quality, hands down. This is a very small little knife that would be good for a backup, or something to have for that &#34;worst case scenario&#34;. Basically, if it comes down to do or die, this little gem will hold up. It's an inexpensive knife, but built very well.
When I heard Jason Brous was working with SOG on a &#34;Silent Soldier&#34; collab, I was really excited. Jason is an absolute prodigy and his blades are very difficult to come by. I was hoping SOG would really take advantage of this opportunity. To my knowledge, Jason has worked with SOG on this Silent Soldier piece and the Triple Threat Fixed Blade redeux.
As I expected, the SOG Snarl is a great knife of high quality. The weight of the knife is awesome and the fitted sheath provides a perfect fit! I'm very happy with my purchase. Don't hesitate on this one!
This knife is comfortable to wear. Was unsure about this as this is my first neck knife. Sheath holds it well, while allowing easy deployment if needed. The only down side was that it wasn't as sharp out of the box as I would have expected. I have purchased several other SOG knives over the years, but I was disappointed in this factor.
Overall I like it. I wasn't impressed with the sheath because it only lets you Carry it in one position, the fit and retention is adequate though. The knife didn't come as sharp as I would've expected and it's a little more difficult to sharpen than the average blade given its shape. It's still my favorite neck knife so far.
The sheath is solid, holds the knife well, and you can deploy this knife easily. I'd say this is a very user-friendly knife that could be handy in a tricky situation. I had been looking for a small tough knife that can be hidden easily and used for unforeseen personal protection while travelling abroad. This knife meets all those requirements. So, I can only recommend it! !
The SOG snarl is a nice little knife that is a very effective, very concealable knife. It fits in my hand securely and is razor sharp. I keep it clipped to my belt in front and under my shirt and I have a nice little knife for all sorts of chores and self defense.This is a great little knife for my collection and I always liked SOG knives for their designs and quality.
As I've read before, this knife does not arrive sharp... at all. It's dull. Also, it's true that the belt clip is not very tight. I took it off and squeezed it shut tighter with some pliers, definitely helped. The sheath holds the knife pretty well, if the knife is ALL the way in. There is a little play area about a mm back from all the way tight, and the knife is not tight and can rattle around.
A reviewer at PoliceOne said that this is really a neckknife- haven't tried it really in that configuration but I've also read that neckknives can slide off your centerline especially  if you're on your back, making them difficult to deploy. Also, I figure drawing from the center/waist is more efficient and gives less of a tell than reaching up under your shirt.And yes, the knife pictured is most certainly NOT the SOG Snarl.
Answer: yes
