A nice little knife to work with, I gave it a sharpen on my wet stones and its like a razor. It has a good feel to it and for the price it's good. Having owned several different Mora's in the past the closest I would say to this one is closest to the Mora Pro Robust in handling and use, another knife I really like.

The GK is a great cutting tool for the money. If you are on a very constricted budget and need just one very strong, affordable fixed blade that won’t let you down, you won’t be sorry if you can get your hands on one of these. Hultafors has its knives made in Taiwan, using Japanese steel. The GK is made of SK5. It’s a good, tough, midrange high-carbon tool steel that one also finds in for instance the Cold Steel SRK; 1080 with whiffs of alloying elements sprinkled in. It can of course rust, just a tad slower than a non-alloyed carbon steel like 1095. Clean and dry the blade at the end of a work session, wipe it with a cloth stiff with old linseed oil and you’ll have no rust problem. I assume it will get a patina over time but have not seen it yet. It is not highly polished, more brushed and that fits the rough function of the blade fine. Fit and finish is the clear weakness of the Hultafors OK4. There is a 1.5 inch gouge on the spine of this particular example reviewed here. This is not a flaw unique to this knife as it is seen on other OK4’s found online. After considerable testing, I feel confident that this is not a structural defect. However, it is a major and unsightly flaw that I am surprised made it past quality control. A second smaller issue is noticeable injection mold seams on the hard green plastic sections of the handle. Ever since Hultafors started making knives, we have strived to offer unique solutions to match specific needs in various crafts. Bushcraft is no exception. When discovering that our craftsmen’s knives had become favorites with the outdoor crowd as well – we got inspired to develop knives especially suited to their needs. The result is a range of knives dedicated to bushcraft and outdoor life. Outdoor Knife OK1 - For tough tasks in the field No beating with a steel hammer in my case, but a fair bit of hitting it with wooden batons. I used it pretty rough in the yard, in dirt, sand, earth, bark, hardwood and softwood. I also tested it on fruit, cucumbers and tomatoes and measured its edge angles. When the wood burner needed some kindling I split that from scrap pine siding with the GK, which it does very well. Cutting bale twine and zip ties, opening bags of animal fodder, light delimbing and murdering cardboard boxes are also in its job description. As is a lot of scraping. Or cutting bundles of high grass, often wet, for our donkeys.The Hultafors GK has a main grind of 20 degrees included (10 per side) and a large secondary bevel - that I measured with an electronic angle tool at 28 degrees included or 14 per side. Sounds familiar? That secondary bevel has the same edge angle as the main grind/bevel of a Mora HD/Robust et al, but it has a far thinner shoulder behind it - the main grind at 20 degrees. So the blade as a whole cuts and slices noticeably better, and is still plenty tough enough. I like my Mora much better." - To each their own, although a Mora with a 3mm carbon blade is twice the price.

I've had this knife a year now and thought I'd write a review. It is a great little knife I have used it for many tasks from splitting wood to skinning rabbits. I use a whetstone to keep it sharp. Worth the money for a good little cheap knife. The cutting edge has a scandi grind for superior sharpness and is easy to re-sharpen. A protective electrophoretic deposition coating (EPD) for best rust protection. The plastic sheath on the OK4 features a fabric belt loop and ferro rod holder. It is well thought out and carries the knife safely and quietly. There is a drainage hole at the bottom, which is a must for any knife and doubly so for a carbon steel blade with large exposed Scandi grind bevels. To aid in extraction there is an excellent external thumb nob to push off from. The angle and placement of the nob are a perfect foil to the tight grip the sheath keeps on the knife. To withstand rust and corrosion the blade has a protective electrophoretic deposition coating (EPD), as well as an engraved scale. The grinded spine of the blade is designed for starting a fire with a fire starter. Oproti jiným křesadlům se jedná o tlustý a dlouhý kus oceli, který dlouho vydrží. (po odříznutí poutka použijete i druhou stranu)The sheath retains the GK very well and shows no intention of getting loose over time. It protects the knife well enough - and the user against the blade, which is vital, and for this price everything else is a bonus. There is a drain hole in the bottom and it has a thumb rest. I have been using it almost daily now for a bit over 3 months, so no box opening review here. Rather a 'long first impression'. I'm really impressed with the feel and quality of this knife. Feels great in the hand and cuts well. For the price it's an absolute bargain. Comes with a nice stealth and belt loop. Yeah I get that it was a joke, but it also came across as an unfair and uninformed description of the OK4.

The finish of the spine is rough, but it scrapes fairly well - good enough for construction work. I filed mine a bit to make it sharper and cleaned the rim at a very shallow angle with a stone, like a microbevel on the spine. Better on naked thumbs like that. Broušený hřbet čepele můžete využít při rozdělávání ohně s pomocí křesadla a na čepeli vygravírované měřítko můžete zase využít při orientačním měření vzdáleností na mapě.Past these two issues, the rest of the fit and finish is quite good. The blade coating was even and well applied. The printing and logos are all crisp and well laid out. The two types of handle plastic are mated well and have not frayed or come loose. Plus, the ribbed texturing on the handle is perfect. As the handle is the stand out feature on the OK4, I am pleased that it was not subject to the major flaw found on the blade. Hultafors Fire Steel FS There are three series of knives from Hultafors that are of interest to someone doing bushcrafty stuff. The lightest and thinnest one is the Craftsman, the typical competition to the Mora Clipper or Companion. It has a slim and fairly thin blade that is very useful for carving and finer work - and it’s still made of SK5 tool steel. The basic Craftsman with a hard plastic handle goes for about 5 euros, the ‘luxury’ HVK-GH version with a grooved rubberized handle costs about 7 euros. The handle is fitted with a Santoprene friction grip for extra control. The cutting edge has a scandi grind for long-lasting sharpness and is easy to re-sharpen if needed. The grinded spine of the blade is designed for starting a fire with a fire starter.
