Good all-round knife

If you're looknig for a great, all-round knife you can use and abuse, yet not cry if it breaks or you lose it, this is the one! Its a tough little blade to be stainless, so you really have to try to break it. The tip will go first, but it isn't hard to regrind one although this will discolor the blade and may affect the temper if you let it get too hot. Great size for general use--not too big to be impractical, but large enough to skin an elk, clean fish or cut rope. Using a baton, you can fell a small tree with this tough little knife. The handle is extremely comfortable and doesn't loosen up (at least on mine), and the exposed parts of its full tang construction are nicely rounded. This is a knife you can comfortably cut with all day with no blistering, and really holds up to Gerber's good name. It's sharp out of the box and takes and holds an edge well, but I personally prefer the edging capability of high-carbon steel over stainless. I suggest re-edging it to take a 20 degree bevel--this makes it more practical for general use and is easier to resharpen under field conditions. I also don't prefer the dual edge blades with the serrations unless its on the back of the blade...would rather have an all smooth design. The sheath is cheap nylon with a hard plastic insert--it isn't hard to find a replacement that fits, but I modified the sheath by just double wrapping about 25 feet of paracord around it, which stiffened it considerably while adding another useful element.If they made this model in high-carbon steel with a single edge and a leather sheath, I'd consider it the perfect field knife.

Great Knife!

I purchased this knife as an all around camp/survival type knife and it has been done that and more! The blade is pretty tough and is still easy to sharpen! It came hair shaving sharp right out of the box! I love the 'grippy' handle, the over molded rubber allows you to maintain your grip even when your hands are wet or bloody. I have used it to gut fish as well as a deer and it worked quite well! I also batoned wood with it and it did the job without fail! Haven't seen any chipping on the blade or tip, as long as your not prying with it or driving it into solid rock or something I don't think you could chip the blade or break the tip off? The sheath does the job of holding the knife in securely and has held up well to heavy use thus far. I was not a fan of nylon sheaths a while back, but have learned that they keep your blade drier in wet conditions than leather does and they don't retain water as long as leather sheaths do after they have gotten wet. I would go with this knife for a survival knife over the Bear Grylls knife which is also made by Gerber, the quality of the Big Rock is superb by comparison. Received the fixed blade version of the Grylls knife as a gift and it fell apart shortly after batoning some wood for a camp fire? I think the Grylls knife is just a marketing gimmick rather than a serious survival knife. If you need a tough all around camp/survival knife get a Big Rock, it will do the job!

Rockin' the All-In-One

First let me say I didn't think I needed THIS big a knife, but like the saying goes, "better to have it and not need it, than need it and not have it".

It's great how it's full tang for when you're driving it into firewood using another log to split wood. It's lightweight and travels very easily. By the way, I'm not sure what earlier reviews talked about regarding the sheath, or maybe Gerber updated that design flaw, but the belt loop is now fully integrated into the sheath (I can't even see where it's stitched!). The inside of the sheath is a hard plastic liner to prevent the knife from piercing through, and there's a strap that comes across the guard to clip the knife securely into place. No probelms with unclipping it either. The ideal razor sharp, general purpose camp knife.

btw: I've actually modified the sheath a little bit. I store a magnesium firestarting tool (yeah, also got it at REI) inside the sheath loop and tied it in with a 2 foot length of paracord. (Same thickness paracord that can fit through the knife handle hole.) If you want to wear the sheath on a belt, just slide the paracord down, it still keeps the magnesium in place.

A great all around knife.

I bought this knife to have a good medium sized fine fixed blade all-purpose knife/tool. NAILED IT! This knife is great in every way it is expected to be. It sharpens very . . . very well, quick and easy to put a hair shaving edge on and keeps it very well. When I shoot a deer, this blade makes short work of gutting, skinning, quartering, back straps, everything. Its heavier full tang design makes it well apt for batoning, chopping wrist thick branches and trees, and chopping fish heads. It feels great in the hand, well balanced and controlled. The grips are soft rubber and removable, I took mine off and easily wrapped the handle in paracord and add a wrist lanyard. With no grip at all it could be made into and hellish spear tip. The sheath is basic but well thought out. It will accommodate any belt, the safety strap is easy to unsnap and flick out of the way, and I can tuck the rest in my pocket and bring the blade out smoothly. Mine has taken heavy abuse and shown it will take much more and it resists rust well. It is an excellent example of one of man’s oldest tools and I am buying more.

Great Knife

I ordered the Big Rock Camp Knife from REI for camping/survival use. I used it last week while I went on a backcountry excursion and it worked well. I used it to cut branches, split 4 in. diameter "logs", preparing food, cutting rope/cord, etc. However, the best use for this was for fire starting. Using the serrations to strike a fire steel, it produced a shower of sparks that ignited dry grass, maya dust, lint, and the like. In 5 mins. I had a fire ready for cooking, boiling water, and for comfort. Using the knife for this will tarnish it, but the tarnish will wipe off. The serrations however, will get damaged. The damage will consist of the points "melting off." The serrations will still be there, the the points will be rounded and warped. But remember, this knife is for rugged use not for show, so don't be afraid to use it and beat it up.
The sheath is all right for what I paid, but its design could be better, but I will try to improve of it like others have.
All in all, this is a great knife, worth well over its retail price and dependable for years of hard use.

Great Knife! Bargain!

I wanted an all around knife which wouldn't cause a stroke if I lost it or something but would also perform the tasks I needed without breaking or falling apart. I have had positive experiences with Gerber products in the past so I bought this one which was designed for Gerber by William Harsey Jr., a well known custom knifemaker! I purchased the knife for a very reasonable price and used it to cut meat, rope, wood, gut fish, cut plastic and wire leader! It was shaving sharp out of the box and is a nice heavy duty mid sized knife! Ergonomics of the handle are great, cut all day with it without discomfort or blisters! The blade didn't dull up quickly and resharpened with ease. The sheath was ok, would have preferred a better quality leather sheath but the knife was good enough so the sheath doesn't detract from it. This knife outdid some knives I have had which cost much much more! Buy a couple of these knives and keep them handy cause they are definitely worth more than the price they are being sold at! One of the better production knives on the market today!

This knife is a tank.

Ive had this knife for about 2 years now. I camp a LOT in the summer and multiple times in the thick of winter, and this knife is a great go to tool.
Ive carved with it, hit the top of it with a rock to split wood, throw it against countless trees, and everything else you can think of.

This is a great knife to just bring along as your beat on knife and as a workhorse. I consider myself a knife guy, i have lots of different types. I found this model to be a solid all around pick, well constructed, sharp, durable, and not too expensive. For the price, this is a solid knife, not the best on the market, but a good knife.

The sheath could be better but it does the job. If you are on the fence on buying this one, just get it. You will never regret having an extra knife, but you will always regret NOT having an extra knife if you need it.... that's my modo.

Exellent knife for the price

You can spend all day shopping for a good quality knife to suit your needs or you can just purchase this one and be more than pleased. Mine has been in the mountains of Afghanistan, the deserts of Iraq, the Cowlitz River Valley and several backcountry hunting trips in Montana and has yet to fail. No matter what you may cut,chop or slice this knife feels comfortable in the hand not matter what grip you are using. This knife fills that void between a camping/backing knife and a blade you may have to use in a survival/self-defense situation. With that being said the sheath needs to be redesigned but with the money you save, you can easily purchase a good quality leather or nylon one of your choice and still not break $100. I have purchased several more as gifts to family and friends who like me don't want to spend a fortune on a knife. Don't pass up a good deal!

The best knife I've ever had for the $$$

For the money, this is onf of the best knives you can buy. I'm back on the web site to order a second one because I left mine on the top of my jeep after packing up at the campsite... god only knows where it landed on the way home. This knife has a full tang, and the hilt has a very comfy grip. I actualy like the flexability of the nylon sheath. At first, I wasn't sure about the serated edge because the blade is made of stainless surgical steel, it's a bit soft and the teeth have a tendancy to dull and chip and are hard to put an edge back on but then aften using it to saw through various things, for the price, who the hell cares. That's the best part, I've had $200+ knives fall apart... again I let this one fall off the top of my jeep...

Honest Review

This was the first "big" knife that i bought. It works great. With a little bit of time on a whetstone and it was sharp enough to shave with--even though there is no good reason to have a knife that sharp... unless you need to shave, I guess.

In all honesty it is as diverse of a knife as I can imagine a fixed blade to be. I have scaled and gutted fish, whittled spears, killed a real ticked off rattle snake, and prepared food with this knife. And after a year of solid use it is as good as new.

Sure the sheath is not the most amazing sheath of all time, though I have not had any real problems with it, but if you want a good knife, you cannot go wrong with this one.

Negative Reviews:

A knife for no reasons!

I own "fierce tools" which are knives upon which you can rely. Especially in a survival situation.

Gerber makes good knives. But this one is a design "cutie" meant to impress the impressionable.

I purchased this, more for curiosity than anything else. Knowledge is power, and the more knowledge one has, the better off one will or should be. I gave it away in short order.

The handle is too thin and not durable. It won't last long with hard useage. The stainless steel blade will never hold a proper edge, and dulls quickly.

The tensile / memory strength of the steel is poor, and the knife will bend or the tip will break when used for heavy prying.

The length is too short to be considered a serious outdoor knife.


A minimum of seven inches - blade length. Preferrably nine inches. WITH AN EDGE WHICH IS 25 TO 30 DEGREES OF ANGLE.

If you can shave with it, it means it's 12 degrees of angle, and good for nothing but shaving.

A zone tempered steel blade which will hold a proper edge during hard useage. And the blade must be of proper thickness. Usually they are.

A tang (handle shaft) which allows you to baton wood, or drive the knife into a tree if lost, for the purpose of viewing the surrounding terrain terrain.

A weight sufficient enough to allow for chopping of limbs and the splitting of "them".

The ability to trench or dig holes - for a fire pit as an example.

The sheath is of little importance, with the exception that you may secure the knife to your hip or pack.

None of these does this knife do. A famous bladesmith, a good knife does not make. Remember he was commissioned to create an artifice intended to cut steaks and chicken and fish.

The old addage is: When the going gets tough, the tough get going. Not this one folks!! Forget it!!

Going on forty years now in the wilderness, I know a thing or two, and I know this doesn't work at all.

Go on line and look at KBAR knives and their Becker products as well. You'll see real knives, and at not much more than this one is going for.

I only wish REI would come to their senses and begin to offer better product knives upon which one can trust their lives to.

The products they offer are cute and nothing more than that.

Good luck with your choice!!

2 problems

The steel is 440A which is a lower quality, softer stainless. The only reason to have a fixed blade rather than a folder is to be able to chop and baton cut as well as slice and cut which can be done with a much lighter folder. Soft steel will not allow much of this between sharpenings. The second problem is the serrations. Short, "combo blade" serrations are too short to be useful but long enough to interfere with all the regular functions of the knife. With this soft steel they are likely to bend in any kind of chopping. Don't buy any knife with "combo serrations". I don't know why REI even carries them. A good quality knife with a sharp blade should be able to cut anything that a serrated blade can, although a full length serrated blade is useful for emergency fast cutting of seat belt straps or ropes. Otherwise the design of the knife is good, and even the sheath is quite functional. The straight, unserrated version of this knife, which REI doesn't carry, would be a reasonable choice for short trips or if you are willing to carry a sharpening stone with you. But there are many other knives, e.g., the Benchmade Rant, in the same weight/size range made with much higher quality steel in the price range just a little higher than this. REI's knife descriptions are not very informative. You should look up any knife you are interested in on the web and see at least what kind of steel it is made of and then check out the properties of that steel. Unlike other categories of gear, e.g., packs and tents, where REI offers a wide variety of choices and usually includes at least several of the best available products, REI's knife choices are, I think, poorly chosen. I think the Benchmade plain edge Griptilians are maybe the only really good choices on the list, ignoring Swiss Army and Leatherman tools which are in a different purpose category. (The Benchade 530s are also excellent knives but too thin and breakable at least for extended backpacking.) BTW, if you are counting ounces at all, don't forget to consider that weight listings for fixed blades (at REI or elsewhere) don't include the sheath. Even the nice light nylon sheath included with the Big Rock brings the total weight up to 8 ounces from 6.3, double or more what a good heavy duty folder weighs.

Best used for camping and backpacking.

This knife was amazing for the first few weeks when backpacking, but when teaching a survival class the knife broke in half while cutting a 1'' tree branch.
wade patten at REI on 06/06/2009

just a knife

Basic knife. It is not the most comfortable knife I have used. I have seen some since I would have preferred for the same money.
