Extrema Ratio serves military and law enforcement communities as well as commercial markets and the knives are well known and sought after all over the globe.

The company prides itself in design, material and quality to deliver a high end product that meets the most severe mil-standards.


The production based on modern cutting edge technology is combined with traditional craftsmanship and the result is the pinnacle of this synthesis. The Extrema Ratio design team uses the 3D system to design new models and create prototypes. Each knife design is then meticulously inspected and then field tested. At this point the finest materials are chosen for durability, function and beauty. Each knife is then hand assembled and hand finished and inspected by Extrema Ratio team of craftsmen.

Each knife that is manufactured at Extrema Ratio has measured up to the Company rigorous standards for quality and performance. The knives are the result of painstaking research and development. This is an Extrema Ratio hallmark. Extrema Ratio knives represent a real, solid value for the money.

All of the knives are made from N690 Cobalt Stainless Steel which is a steel from a small plant in Austria, often used in the manufacture of surgical instruments. This steel along with their tempering methods produce a steel of great strength, flexibility with the capability to take and retain a razor sharp edge. The handles provided on the fixed blade knives are made from a grip polymer called Forprene which provides a very sure and comfortable grip even when wet. The folding range of knives have a shell made from a super strong anticorodal alloy and the best materials are used throughout to ensure reliability and longevity.

What Knife Should a Prepper Carry

What Knife Should a Prepper Carry

by Leopold Lacrimosa

I was asked by a group of preppers to write a short article on what kind of blades should one carry in time of need. After giving it much thought, I’ve come to the conclusion that if SHTF time you should be prepared by carrying several different knives on your person.

Let’s look at the ones I would and do carry. First off, deep down in my pocket I have a traditional 2 blade pocket knife. Now the one I use has beautiful Mother of Pearl scales on it. I pull it out to use, I don’t get the dirty “why is he carrying a weapon” look for these social minded liberals. Rather I get the “Ooh, that’s a pretty knife!” instead. But if I think I’m going to be needing it in a bit stronger situation, I switch it out with a 3 blade stockman pattern knife with stag scales. This way I don’t have to worry about damaging the MoP scales. One of these knives are always on my person. They’re not big knives but are able to do most daily cutting jobs I come across due to the variety of blades. Style wise, size and blade count are all a matter of personal choice. Remember the lager the knife the heaver it sits in your pocket. Usually, a Jack knife has one blade while a Trapper has two. Stockmans are known for three blades and a Congress has four. On this knife, a modest $60- $100 should get you a good knife.

I almost always have a top quality Tactical knife clipped to the inside of my pants pocket. (I take it off when I go into buildings like schools and such and leave it in the car til I get back.) This should be a mid-size knife with a blade about 3.5” – 4” in length. It should be of good quality steel, no less than 0.14” thick blade. The handle should fit in the hand comfortably. Since my hands are different than everyone else I can only recommend you pick up the knife you are interested in and hold it in your hand. The handle material should be tough such as Macarta or G-10 not wood or bone, both which can chip or splinter under duress. The blade locking mechanism needs to be strong. I suggest you forgo a liner lock unless there is a built in secondary lock you can engage. Back locks are usually the strongest though I’ve seen some truly strong rolling locks. Though automatics and auto assist knives are cool and fun, you’ll have a piece of junk when the spring breaks. In this range of knife you should be spending $150-$300 range.

The next knife you should have is a fine fixed blade multipurpose knife. When I say multipurpose, I talking about a knife to do a multitude of jobs from daily camping chores, to heavy cutting to even defending yourself with. The knife should be of the best quality carbon steel and make. The blade should be 6” – 8” long. It should be a straight edge. The spine should be 1/4” thick with a full tang. The handle should be solid material. Stag is ok in this because of the thickness usually used in a handle of this size. You got to remember it worked well for the deer or elk for many years. Mammoth tooth is strong but it adds a lot to the price of a knife. A guard is recommended. Even a double guard. I personally recommend a clip point Bowie knife. Good for use in skinning an animal yet large enough to fight with. Intimidation helps when in a fight and a Bowie is high in that factor. For this I prefer a custom handmade knife over a factory model not to say there are not some good fixed blades out there that are factory made. You must certainly go with reputation in the case of who is going to make it for you. Price range should be $200 – $500. Anything priced over that and I want to put it on a shelf for display purposes only.

If you carry a secondary fixed blade knife then I would suggest a double edge dagger. A dagger has one purpose and one purpose only. Smaller than a Bowie it can be used in your other hand in conjunction to your Bowie.



Last but not least, everyone needs a good quality hatchet for general chopping work. It will help save the edge on your knife. Remember, I said hatchet not an ax. A hatchet is intended for light chopping, such as small limbs or bushes while an ax, depending upon the head size can be used for for chopping jobs of all sizes, and some ax heads are even double-bitted to increase the work interval between sharpening. The main difference is weight and size. A hatchet you can carry without to much problem but I’d hate to have to lug an ax around all day especially if I need a hand free for a rifle or gun.



The last knife I recommend but it is not necessary to have is a machete. Great to have if your into surviving in the jungle but remember, if your name is not Danny Trejo or you’re not planing on trekking through the wilderness, there is a lot of other equipment you may need to carry instead. This is optional not mandatory.

Basic Folder 2

Extrema Ratio
Our knives are built with the most current high tech manufacturing processes. Each Extrema Ratio knife is a blend of the finest materials available and a commitment to craftsmanship. When it comes to knives for survival use, one of the most important requirements is that the knife should be strong. Built to last.

Basic Folder 2 – Black

This series of “full size” folding knives are suitable for professional use by the military or police. The handle is solid and comfortable, the clip is reversible and close, in the case of the BF1 e BF2, it becomes a useful and comfortable resting point for the thumb in “reverse grip”. There are two blade patterns: Tanto and Drop; and two patterns of handle: Classic and Tactical. The “Tactical” handles are characterized by a milled design of concentric circles with perforations for lightness and high grip. The “Classic” handle is full with the characteristic lowered flat zone to enable the use of the opening “pin” without emerging from the profile of the closed knife. All the blades are burnished through zirconium carbonitruration, the handles are burnished through anodization. The blade blocking mechanism is the approved “liner lock”, assisted by a manually activated security mechanism protected by a “carter”.
WEIGHT: g 85












Blackhawk! Blades Pointman

The Point Man is both the rebirth and the evolution of a true classic—the original MOD® “Trident” utility folder. The signature ergonomic handle shape and distinctive spearpoint blade of the original design are now rendered with all-new materials, including CNC-machined textured G-10 handles, nested 420J stainless steel liners, and a black Teflon®-coated AUS8A stainless steel blade. Other enhancements include improved lock geometry for its heavy-duty liner-lock mechanism and the addition of a four-position clothing clip that supports both left and right-side, tip-up and tip-down carry. Improved features and a very affordable price make the Point Man an outstanding full-service tactical folding knife.



Blade Length: 3 3/8" 
Overall Length: 7 7/8" 
Blade Material: AUS8A stainless steel. 
Blade Finish: Black Teflon Coating with Point Man and Black Hawk name on it. 
Edge type: Partially serrated with Dual Thumb studs. 
Handle Material: 420J stainless steel liners nested in textured G-10 scales. 
Pocket Clip: Right or left-side, tip-up or tip-down carry. 
Made in Taiwan.

GEC Equestrian’s Trapper Knife w/Exotic Mexican Bocote Wood Handle

So I log into iKnifeCollector.com the other night only to come across a conversation between Hog and Tuna about a GEC knife up for bid on ebay. They were wondering if the knife was really a GEC knife or not. I did a quick internet search and came up with info showing it was a real GEC knife and shared the info with the guys. But, they still declined to make a bid which was ending in a few minutes. So I placed the bid and won the knife.

With a little more research, I found out that the knife was made in 2009 and only 35 pieces were made. Pretty happy that I bid and now am awaiting the arrival of my purchase.

EDC Pocket Knife

Since I work teaching chess in the scool districts, I’ve received lots of flack for carrying a tactical pocket knife, (One that clips to the inside of m pocket which can be seen), so I’ve desided to switch to a classical pocket knife (one that sits on the bottom of my pocket and can not be seen). After much thought, I went with a Bulldog Brand Groundhog Knife ( 3/8″ Groundhog knife comes with a master blade laser etching of the “fighting dog” logo.  The handles on this piece are genuine exotic Pearl.  440C
Surgical Steel razor sharp blades on this knife.) A really smart choice.
