The GSO-6 is not currently available. Be sure to sign up for our newsletter to receive an email when this model is in production again.

We've taken the already outstanding SURVIVE! GSO-6 and made it even better. While the blade profile has remained roughly the same, we've lengthened and recontoured the handle a bit to improve comfort and usability over a wider range of users.

The SURVIVE! GSO-6 is designed for those who like the size of the GSO-5.1 but don't prefer a finger choil. Like the GSO-5.1, it is a full sized medium utility knife, ideally suited to folks with medium to larger hands. The robust, well balanced design of this tool allows you to tackle a wide variety of tasks with relative ease. The very manageable size and weight of the GSO-6 is solid and confident in your hand, without being heavy or feeling bulky.

Our high quality Torx T-25 style fasteners are precision machined from 17-4PH stainless steel.  Key features of the kydex sheaths include: excellent retention, drain channels, and several attachment options with slots and eyelets, in addition to the kydex clip.  The satin stonewash finish on the blade provides extra durability while maintaining a sharp enough spine for use with most ferro rods.

A bit about the steel used in SURVIVE! Knives:

CPM-3V is a high alloyed tool steel, made using the Crucible Particle Metallurgy process, that has a very high impact toughness and excellent edge holding. Being made with the CPM process, this steel is also very resistant to lateral stress (flex) breakage, making it a perfect choice for a high performance, hard use knife. CPM-3V is not a stainless alloy and can stain if not cared for.  Check out the CPM-3V Data Sheet.

SURVIVE! proudly supports Peters' Heat Treating for all of our heat treating needs.

GSO-6 is off balance
Written by Steve M on May 31st 2022

Compared to the GSO-7 (my favorite GSO knife) the GSO-6 is off balance. The handle is too large for a six inch blade. The knife is well made but the feel as a result of a disproportioned handle size makes the knife feel awkward in the hand. I hope this isn't the case for your newer knives. knives at this price range need to aesthetically pleasing and balanced in the hand. Personally, I prefer a knife that is slightly blade heavy.

Superb knife for hunting & outdoors!

If you want to carry one fixed blade that will allow you to do any type of outdoor/hiking/hunting tasks, the GSO-6 is the best option. I tested one with CPM 20CV blade steel and it performed great, maintained edge well during various tasks. However, I would prefer 3V blade steel as that's my most preferred outdoor steel. The overall length and weight works perfectly, especially if you are someone that carries few knives of different sizes and is looking for one perfect universal fixed cutting tool - this is the one! GSO-6 anytime! 5 Stars! Proudly made in USA! Superb Quality and Craftsmanship - No need to say more!

Awesome as usual

Short and sweet.....survive blows all others out of the water. I received my GSO 6 in the beginning of December and i have been using from food prep to butchering deer to clearing small brush and it performs as expected. My 6 is 20-cv with ghost jade handles with the green kydex sheath and holds an edge great even when boning deer out. When i first got into Survive i wanted the 5.1 and the 8 but that turned into 12 after seeing the quality and value of these knives. Now my wife to my grandchildren all have GSO'S. Great job Survive in all aspects! Worth the wait!

My new favorite knife
Written by Matty J on Jan 19th 2022

Before I get into the details, I’ll just say this GSO 6 is my ideal knife. It is perfect. The dimensions and materials and attention to detail could not be any better. I really think that if I tried designing my ideal knife, I’d end up making a GSO 6. I experienced the usual, very fast and free shipping from S!K. Secure packaging with the crinkle cut paper that I’ll use to start a fire this weekend in my fire pit to roast some s’mores with my kids. Shaving sharp out of the box? Check. The new tumble finish is great. Everything I love about the old finish is here. Textured handle finish looks good, feels good and works well to provide traction without hot spots. I’ve poured over specs for years, but the numbers don’t show how great this handle is. I love the versatile length and for my smallish-mediumish hands, the swell and contouring are perfect. The handle is beefier than my other GSOs, but just like my new spec 4.1 and 4.7 all three fit my hand well, just differently. I really appreciated the 4.7’s added handle length compared to the old 5. I was blown away to find that the GSO 6 handle is actually longer than my ESEE 6’s. I know the GSO 10 is designed to be the one tool option of the family, but I don’t think there’s much this 6 can’t do. With the handle and blade length and strength of the blade, I think it could be pushed into any knife type job and do it all well. This is a survival knife. The balance is exactly where I like it, just behind the top handle screw so it really is a neutrally balanced knife. If I hold it at the right angle and open my hand, it balances perfectly on the swell below my index finger. The sheath is as amazing as all the new spec sheaths have been. Zero rattle. Great click, yet easy to retrieve the knife. The new belt clip is an awesome improvement. You can see how much space is left over when I put it on a 1.5” wide belt. To touch on a few things I’ve seen in this group, I can’t find any sense of a hollow grind. This is a flat saber grind. The sharpening choil may be a small design consideration compared to things like handle contours and blade geometry, but this tiny choil seems like the best one on the GSOs that I have. You can see this knife does have the delta heat treat. I was sad to see that S!K is moving away from the delta, but I also can’t sense a difference in my delta 3v versus my 2015 3v. I like the idea of delta, but in use, all of my SURVIVE! CPM 3v is outstanding in all steel properties. My old 5 is still going strong after years of hard use. No complaints. I’m really anxious to get out and use this thing. I anticipate I’ll have a great time whittling, carving, slicing, chopping and batoning. With this knife and a saw I could survive in the wild for hours, if not an entire afternoon or whenever I run out of snacks. I’m just so happy right now, I can’t put this knife down. All my expectations have been exceeded. Bravo, Guy and Ellie and team

Best knife ever
Written by John D on Jun 1st 2021

I received my gso 6 in black and orange g10. First of all its fit and finish is impeccable. They kydex is like perfect. Which we all know kydex is hit and miss. The balance and feel is like nothing I have ever experienced before. The finish is absolutely unprecedented. I have put a lot of hours of hard use in a short amount of time. And it still looks brand new. It is just an unbelievably slick peice and super fun to use. The edge retention is outstanding. After all the use I have had with it, it still remains as sharp as it was when I got it. The people over at survive are producing the best knife I have ever had the pleasure of owning. And I'm looking forward to them getting over a lot of the unfortunate setbacks they have had so they can deliver more of their products. Im already in the process of ordering more of their knives and cannot wait to enjoy more of what they do so well. Thank you everyone as survive. And a shout out to Guy, who was super awesome with his customer service and making sure I was totally happy with my purchase. Keep it up survive team. You are amazing.
