From time to time i receive questions on what combinations are the best in general. One of my educated schooling and what I wanted to do research on is functionality. By this I mean functionality on SAKs, combination tools and fixed blades. There is always a room for evolving the knowledge.

Today one of the best combinations for a person that is a bit prepared for EDC, outdoors-tasks and selective crafts work is the Multi-Tool and a fixed blade knife. Doing so it can be interesting to find a choice that can be cost effective and still be a serious package of tools with quality. Getting a SwissTool may cost some money for the wallet. It is worth every dime in my opinion because it is balanced in quality and cost. I was a bit curious on the Hultafors fixed blade knife in carbon steel. I found many videos on youtube and I discovered many discussions on this several places. Here in Norway we are very glad for the Helle and Brusletto Companies that makes high quality fixed blade knives for all situations. We are also very fond of Mora knives from Sweden that you can find in most hardware stores across the nation.

 The Hultafors Brand is also well known here but not near as known as the Mora blades are. They are gradually getting more known during the last years. I knew from before about the name and I have seen different models available for craftsmen and outdoors people. Never the less I noticed a new knife called the OK4 outdoors knife with what should be a SK-5 Carbon steel 58-60HRC. It is pretty much an all-round fixed blade knife with a solid hidden tang construction. It is so solid made that it can be used for batoning. That is not my favorite knife use anyhow. That a side I was very curious about this knife and I ordered one. It is a bit more expensive than the Mora knives. It is still a low cost for the quality. Out of the box it was sharp but not as sharp as I hoped for. I polished the edge some and the sharpness increased significantly. It only took a few seconds to get the touched up edge to what I feel is best for a new knife. I only did minor cutting tasks to feel the steel and handle. It is good! The blade is measured to be 3mm+ with a digital caliper.

There is no need to test it fully because I know about several places this already have been done so with a good result. It is a hard use fixed blade knife that can take it. In my quest for combination tools for Multi-Tools I am rather sure and glad to have found a good one with this fixed blade knife. This knife is already made preparations on from the factory for a firesteel. It even got a little loop in the fabric holding the sheath for it. If you also use the bit driver and key together with the MTs then I feel it is a serious package all together.

Using carbon steel on fixed blades is ok because it is much easier to clean compared to a SAK or a MT. Today I believe many Stainless Steels are side by side with carbon steel for the cutting abilities on wood and other materials. I will never believe this knife to be better than Helle and Brusletto. I do feel it is a very good cost effective combination choice. There is no doubt that the hardening of this blade is correct. This I could feel doing the polishing or light sharpening to bring the factory edge complete. This or the Mora Robust are excellent choices for several combinations if you ask me.

The handle is comfortable and the sheath is interesting as well. It got a cool mechanism!

The blade got a Scandinavian grind and the blade is black coated. Some mineral oil from time to time will secure the corrosion resistance. Wipe the blade after use. Out of the Box i only had to touch up the last section of the edge without disturbing the design of the edge.


Over the years i have used several Scandinavian fixed blades from Helle, Brusletto and Mora + others. For fishing I have used the fixed blades, SAKs and MTs.

The typical Scandinavian handle is made of wood that is warm when it cold and it is ergonomic. It is a safe handle. The handles made out of wood are typically birch and the design of the handle should be extra comfortable and safe. These knives are excellent for outdoors and fishing tasks. Many times the handles are all-round types for absolute everything.

Over the years I used several Mora knives with stainless steel and handles made out of a combination plastic and rubber. These are very slip resistant when doing fish.

Wenger and Victorinox used and use rubber inlays and combination handle scales to increase the safety, comfort and design.

The Hultafors handle got a combination of plastic and rubber. The rubber is soft and comfortable, not to forget slip resistant. When you are doing harder cuts you can feel a slight motion upwards and the grip of the hand sinks into the material and locks the hand completely. The only little drawback if I could say so is the feeling vs. the edge. When force cuts with precision the little movement of the rubber can disturb some. I doubt it to be of any importance.

The blade feels very sturdy doing force-cuts!


The handle is safe and it got sturdy plastic under the rubber. The sheath is a combination fabric and plastic. The plastic sheath is very similar to the ones you find on Mora knives. They work ok and you can do several modifications on it and have ways of carrying it.

It is very smart even if this is a coated carbon steel blade to use some mineral oil on it from time to time. Clean the blade with some soap and warm water. Let it dry and put some mineral oil like Vaseline Oil medicinal oil on a cloth and wipe the blade. Then it can be placed in a dry sheath. The last mentioned is important because it is typically that plastic sheaths are hard to dry. This may sound strange but it is a fact. It is weird how water inside it can stay there for some time even if it is dry air in the room. Just give it some time to dry properly and use a flashlight to see inside before placing the blade secure in a sheath. Carbon steels are typically easier to harden than stainless steel. Carbon steels can corrode easy without maintenance from time to time. This is a coated blade like mentioned and therefor you will not get patina on it. Patina usually develops on such steels. Coated blades are fine and it may help for protecting the blade from rust. I would strongly suggest maintenance and using oil. It is a good thing. Carbon steel blades without coatings will typically get discolorations on the blades from substances in wood and materials you cut.


Leather sheaths thats been properly treated will not take up water easy. If a leather sheath first get wet then it will for sure take longer time to dry than plastic and then you must not have the blade inside it. From experience the leather will not shrink and if it does it will after wax and leather fat become correct again.



It is a tested fact on scandinavian blades that wood handle and well treated leather will last a very long time. Leather can many times outlast Kydex!


I am very pleased with this OK4 Outdoor knife. The sheath can be dried with air or a device you make. Because it is not as much in contact blade vs. sheath it will be sufficient carry. Kydex sheaths for example that is a tougher material many times got the blade in contact with the kydex. In the outdoors over time it can be difficult to keep it free from particles and water. In the field carbon steels and leather sheaths share a very special relationship. If you place a wet blade in a leather sheath then the leather will dry the blade. It is tested in the field vs. kydex material that will keep the blade wet and you get rust or corrosion.


I hope you enjoyed this talk today and hopefully I gave some good tips. Remember that leaving wet knives in plastic sheaths are usually how they start to corrode. It is not enough with a drainage hole in it to keep it dry in the outdoors. It can be smart to wipe the blade before putting it in the sheath. I really like the OK4 sheath, do not get me wrong. It is a nice carry and the blade does not make very much contact when in the sheath either. Typically if you are in the outdoors in wet conditions it is unavoidable getting everything wet and once you are indoors you can dry everything fast if you know what to do.

Carbon steels love medicinal white oil like Vaseline oil. It is also excellent to use to clean a blade. Use some oil on a cloth and be rich on the blade. Wipe it clean and then use a small amount on the blade again. The advantage with using carbon steel on this low cost knife that did cost around 190NOK is toughness and good abilities on wood and several materials. It is difficult to get a stainless steel blade for the same cost that got these abilities. If you go up in price range then the stainless steels improve. There are several types of carbon steels and today you can get high end ones that got super extreme abilities. I know without testing personally that this OK4 is tough enough.
