ABOUT SOG Our story begins in Vietnam, where members of a highly classified US special ops unit - known as MACV-SOG - carried a unique combat knife into the jungle on covert missions. Years later, in 1986, that knife inspired a young designer, named Spencer Frazer, to found SOG Specialty Knives. His mission: to reproduce the original SOG Bowie knife and pay tribute to the special ops unit that created it. What began as a single commemorative model soon became a full line of innovative tools - field-proven by US Special Forces, even honored as the Navy SEAL knife of choice. Today, SOG knives are carried with confidence into the most demanding situations. Forged out of tradition, hardened in the field, honed for you. Review: great knife - Great knife. Good steel, better (more stainless) than the alternatives I was looking at for humid environments. I already had good experience with Buck 440c. It came sharp and ready to use. The sheath is good. The fancy clip is bit floppy but no issues with the screws (once I found the proper torx bit). I actually removed the clip and its mounting fixture. This way the knife and sheath are quite slim and carry well in a front pants pocket. Review: SOG is back. - SOG has undergone a major rebranding and it is working. This is not the same SOG, it is a new and extremely improved SOG. The Tellus FX is no exception to this, a new design that's available in a fixed blade (this one) and a folding version. I am impressed enough with this version that I will soon be getting the folder too. The sheath is also an improved redesign, the belt clip is an easy adjust type where you can adjust for regular belt carry to scout carry and almost every angle of carry in between. The knife fits in smugly with barely any wiggle, but still easily removed when you need it. Another positive is how sharp it comes right out of the box, it is extremely shaving sharp. Feels good in the hand, very good ergonomics. All of this for less than $50, crazy value. Can't wait to get my folder. ## Features - A RUGGED FIXED BLADE KNIFE - A perfect companion when you need a brawny solution for those down-and-dirty jobs when you're off the beaten path; the full-sized Tellus FX is a high-value and dependable fixed blade knife that comes big when you need it most - CRYO 440C STAINLESS STEEL - It has the perfect combination of outstanding corrosion and wear resistance that is required for a knife destined for hard outdoor use; the stonewashed finish offers increased corrosion resistance and hides scratches - GRN HANDLE - Nylon material for knives boasts of its strength, impact resistance, chemical inertness, and stability at high temperatures. glass fibers added to the nylon create a new and even more rugged material, glass-reinforced nylon (GRN) - UMS COMPATIBLE SHEATH - The sheath incorporates the best parts of SOG's Universal Mounting System, allowing secure, customized carry on a wide range of outdoor adventures; this sheath ensures that your tools are always within reach when you need them most - AT HOME IN THE FORESTS OR THE FIELDS - From bushcrafting and camping to survival and tactical applications, the SOG Tellus FX Fixed Blade Knife is ready to tackle any challenge you throw its way; rugged construction and superior performance ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09SGJPQFS | | Age Range (Description) | 18+ yrs | | Age Range Description | 18+ yrs | | Best Sellers Rank | #100,376 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) #200 in Fixed Blade Hunting Knives #412 in Camping Folding Knives | | Blade Edge | drop point | | Blade Length | 4.25 inches | | Blade Material | CRYO 440 Stainless Steel | | Blade Shape | Drop Point | | Blade Type | Non-Serrated | | Brand | SOG | | Brand Name | SOG | | Color | Blaze | | Customer Package Type | Standard Packaging | | Customer Reviews | 4.6 out of 5 stars 203 Reviews | | Hand Orientation | Ambidextrous | | Handle Material | Blaze Orange GRN | | Included Components | TELLUS FX - BLAZE | | Item Length | 10 inches | | Item Shape | Rectangular | | Item Type Name | Knife | | Item Weight | 190.06 g | | Manufacturer | GSM Outdoors | | Model Name | Tellus FX - Blaze | | Model Number | SOG-17-06-03-43 | | Number of Items | 1 | | Orientation | upright | | Part Number | 17-06-03-43 | | Power Source | hand_powered | | Product Care Instructions | Hand Wash Only | | Recommended Uses For Product | Bushcrafting | | Reusability | Reusable | | Size | 4.3" | | Special Feature | Full Tang | | Special Features | Full Tang | | Style | Tellus FX | | Theme | Outdoor | | UPC | 729857014106 | | Unit Count | 1 Count | | Warranty Description | Lifetime | ## Product Details - **Age Range (Description):** 18+ yrs - **Blade Material:** CRYO 440 Stainless Steel - **Brand:** SOG - **Color:** Blaze - **Handle Material:** Blaze Orange GRN - **Included Components:** TELLUS FX - BLAZE - **Model Name:** Tellus FX - Blaze - **Recommended Uses For Product:** Bushcrafting - **Special Feature:** Full Tang - **Style:** Tellus FX ## Images ![SOG Tellus FX Full-Sized Fixed Blade Knives 4.2" Full-Tang CRYO 440C Steel Blade GRN Handle UMS Compatible Sheath - Image 1](https://m.media-amazon.com/images/I/51p4N9A8dxL.jpg) ![SOG Tellus FX Full-Sized Fixed Blade Knives 4.2" Full-Tang CRYO 440C Steel Blade GRN Handle UMS Compatible Sheath - Image 2](https://m.media-amazon.com/images/I/6153i5S0w0L.jpg) ![SOG Tellus FX Full-Sized Fixed Blade Knives 4.2" Full-Tang CRYO 440C Steel Blade GRN Handle UMS Compatible Sheath - Image 3](https://m.media-amazon.com/images/I/61m8YEErAgL.jpg) ![SOG Tellus FX Full-Sized Fixed Blade Knives 4.2" Full-Tang CRYO 440C Steel Blade GRN Handle UMS Compatible Sheath - Image 4](https://m.media-amazon.com/images/I/61FymN1IvNL.jpg) ## Available Options This product comes in different **Color** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ great knife *by S***D on April 5, 2026* Great knife. Good steel, better (more stainless) than the alternatives I was looking at for humid environments. I already had good experience with Buck 440c. It came sharp and ready to use. The sheath is good. The fancy clip is bit floppy but no issues with the screws (once I found the proper torx bit). I actually removed the clip and its mounting fixture. This way the knife and sheath are quite slim and carry well in a front pants pocket. ### ⭐⭐⭐⭐⭐ SOG is back. *by E***E on December 4, 2022* SOG has undergone a major rebranding and it is working.

Can't wait to get my folder. ### ⭐⭐⭐⭐⭐ Great tool *by M***. on April 15, 2026* I purchased this as a camping knife for general camp tasks, I've put it through some testing on my day hikes, and it functions well, I didn't notice any hotspots on my hand after use, it retained its edge and was easy to touch up with a sharpening stone after extended use. the Sheath is decent and I like the fact that it can be used ambidextrous and in multiple positions. I will probably purchase one for my son prior to my next camping trip. ## Frequently Bought Together - SOG Tellus FX Full-Sized Fixed Blade Knives 4.2" Full-Tang CRYO 440C Steel Blade GRN Handle UMS Compatible Sheath - SOG Small Fixed Blade Knife - Instinct Boot Knife, EDC Knife, Neck Knife, 2.3 Inch Full Tang Blade w/ Knife Sheath and Clip, 4in. x 1in. x 8.5in.
