Outstanding
I’ve had the knife for 3 months now to replace one of a similar vein, a Morakniv companion. Hultafors’ option is superior in basically every way. The sheath is pretty standard plastic, but it’s separate from the belt loop, which is great for me due to knife laws where I live. Quick on/off. The knife itself is fantastic, I don’t know how they make them so good at the price point. The handle is comfortable, with a good texture to give you a secure grip. It really never feels like it’ll slip out your hand. The blade itself takes and holds an edge very well, it came sharp but only took 5 minutes on a 1000/6000 grit whetstone to be sharp enough to shave. It held that edge through a solid 4 days of use on a camping trip where I used it pretty much non stop all 4 days. The only flaw, and I use “flaw” VERY lightly, is it’s a touch dented on the spine from being hammered through wood. This isn’t really a flaw of the knife itself, had I used a bit of wood the way I’d usually do it would’ve been fine, but I had a framing hammer to hand and used that instead. The dents are minor and I could really fix them, I just don’t care to. A must buy at a price point that hides the sheer quality and robustness of the knife. For me, expensive blades are for chefs. For an every day fixed blade I want a number of things and this ticks every single box.

Strong, reliable, sharp - a knife you can depend on
A great, robust, workhorse of a knife. Perfect for abusing in the outdoors - i use mine around camp, and for bushcrafting tasks. The scandi grind is perfect for carving. Makes lovely feathersticks. Comfortable grip, wet or dry. Keeps a decent edge, just a little stropping needed if it starts to dull. Even comes with a ferro rod. Whether you're starting your bushcrafting journey, or just want a knife that you can abuse - this is for you!

Not bad
Feather sticking I'd give a 6/10 Battening I'd give a 7 Comfortable grip Decent sheath with fire steel, works as it should, a great buy for beginner fieldcraft and bushcraft. Does need to be sharpened a bit more out the box though

Reliable and value knife
I purchased this knife after comparing different products and their reviews. Upon receiving it I was thoroughly impressed. Pretty sharp out of the box, a couple passes on my hone and strop and it was good enough to shave. After putting it through its paces with whittling and using it to baton kindling, it's held up really well. Always comfortable in the hand, the handle is a great size and the texturing feels secure. The blade is a good size, the black coating is fairly durable but is wearing off on the spine. As the knife is carbon steel it should be kept dry or it will rust in these exposed areas. The edge retention is good, it sharpens quickly, the point alignment is decent. For the money I'd say this is as good as it gets.

Proper review
This is a perfect knife if you are in the building trade really high quality steel. The sharpness is unparalleled. If you haven’t used hultafors tools before you must try them I guarantee as someone who’s used these tools for over ten years you won’t be disappointed and will end up buying more. I can’t fault them and would highly recommend.

Not sharp by any means
Pro’s - is a knife and not horribly expensive Cons’s - out of the box I have spoons that are sharper than this

Heard and saw the reviews on this knife and took the plunge. Batoning: able to baton but only can be done to smaller logs Feathering : does a great job Filleting : Does the job but not the best cut Will recommend for the casual camper who needs a knife to get things done around the campsite . Not your FX-1 or ESEE . But it’s a heck of a workhorse

今まではモーラを使用していたのですが、ナイフの峰でファイヤースターターが擦れるナイフを探していました。 と言ってもリーズナブルに越したことはなく、また切れ味と見た目も気になっていました。 そして見つけたのがハルタホースのこのナイフです。 探し始めた時の条件の他に、ファイヤースターターが装着できる、他人と被らない、刃が黒いので火花を散らした後の汚れが気にならないというオマケも付いてきました。 フェザーは僕の腕の悪さを除けば普通に作れます。フルタングではありませんがバトニングも問題ありません。 オーバースペックではない、とても使いやすいおすすめのナイフです!

Someone at Hultafors had the bright idea to marry the GK blade with the HVK handle. I ordered it without actually holding it in my hand. When I received, I was disappointed to see that the handle was exactly like the HVK's. It has the ridged rubber overlay, which I despise. I find rubber leads to lots of hotspots and sore hands. It's also made for small/medium hands. The good, the blade is tough as nails. I like that it's coated, to protect against corrosion. The spine is squared off, so you can use it with a ferro rod. It also didn't have the secondary bevel that the GK does. Is it worth double the price of the GK? In my opinion, no, but it's a decent alternative to the much more expensive Mora Bushcraft Black. If I could do-over, I'd get the OK1. Same blade, much bigger handle with no rubber. If you already have a GK, sharpen away the double bevel & save your money.

Cuchillo excelente, pequeño (9cm de hoja aproximadamente) , el mango es genial, el mejor grip de todos cuchillos que he probado. Espiga oculta que llega a los 2/3 del mango (hasta la A de hultafors) comprobado con imán. Sensación de robustez y consistencia que no Dan otros cuchillos similares (morakniv, baco, etc....) totalmente recomendable para compra , sea uso casual o intensivo. He cortado troncos de 20cm de diámetro con corte transversal para probar y pasa con nota, batoneo limitado por hoja pequeña, pero el cuchillo aguanta. Lo llevo al campo siempre y no te deja tirado. Un pequenajo para ir al infierno y volver con el. Un precio muy ajustado para la calidad recibida. Gracias

Finally found a decent priced OK4 to try out. Am impressed with the compact size, that feels comfortable in my size large hands. Blade was sharp out of the box and appears to be very sturdy. Tested the edge on blocks of black and honey locust. Which it performed well on both type woods. As some folks have pointed out, the sheath is adequate. But like Morakniv, Hultafors has focused it’s priorities on the knife itself. I do like how Hultafors added the nylon ferrule rod harness and belt loop. That makes this sheath a step above Mora’s sheath. Overall, a great knife at the price point.
