The F4 is our general purpose bushcraft style survival knife. Its 4" blade is robust enough to withstand the toughest survival situations, yet refined enough to breeze through any bushcraft task. This version is constructed from 5/32" thick CPM MagnaCut stainless super steel, making these knives exceptionally durable with best in class corrosion resistance and the impeccable edge retention you expect from a premium stainless steel. The blade features an attractive polished stonewash finish that helps keep your knife looking like new. We leave the spine sharp enough to rain sparks from a ferro rod or scrape cedar bark for tinder. The sturdy full tang is skeletonized to reduce the overall weight of the knife, making the F4 an ideal carry companion in the field or around town. You'll find the ergonomic 5" handle has no hotspots, providing a seamless interface between your hand and the tool. The textured natural canvas micarta scales provide a soft, organic feel in-hand and a sure grip in wet conditions. Whether you're crafting a bow drill or field dressing an elk, the F4 will get the job done right.

First, I wanted to say thank you for the military discount the owner (Stu Shank) gave me once I emailed.
You know when you pick up a knife that not only looks good but feels good? That's this knife. Looks great and cuts easily. The grip feels great in the hand and I can't wait to actually get some field time with this. If you're looking to splurge on a high quality blade then do it. You won't regret it! I'm considering getting another kind of their blade once I have more time with this. Love it!
P.S. will try to leave another detailed review once further testing is done.
Excellent knife, razor sharp out of the box. The leather sheath is stunning.
This knife will do everything I need at a camp from baton to slicing tomatoes! I fully expect my Grandson will be using it when he takes his Grandson camping…. Great knife!
I am pleased with the build quality as well as the rotating sheath.
The knife is amazing and love the leather sheath zero complaints at all just outstanding quality and loved that they even put a personalized thank you card in the box. My previous comment I was disappointed with lack of communication on there fb page when I asked a question and didn’t get a reply. Turns out they had bin hacked and didn’t have access to there account during that time. Once they saw my review Stu took the time to send me a personal email to apologize as well as reply’s to my review and again replied to my comment on fb once they regained access to there account. I deeply respect that he took the time to respond to me in morays to make sure I heard from him and knew how sorry he has for not being able to respond to my questions shows great care in a company when they ceo take the time to personally respond to a problem and regret saying anything bad in my first review. The knife is amazing as I said before and feel it will definitely last a lift time I have large collection of knife and had a favourite fixed I used for hunting that i never though I’d replace till I held f4 in my hand just a outstanding knife all around and will be my new favourite for years to come. Definitely recommend getting one if you can
