    The knife is beautifully presented in a wood box. This knife and sheath are a work of art.

    The most well thought out back country knife we've handled. The 90° edges on the spine (except for on the handle- bonus point) are sharp for making quick tinder bundles and a perfect strike point for a ferro rod. The craftsmanship and value in this exceedingly sharp package is just outstanding.

    After buying and selling a fair few knives trying to find the knife to rule all I happened across white river knives. The ursus 45 is essentially perfect. The S35VN was immaculate and razor sharp, and has been maintained shaving sharp with a fine ceramic and a strop despite being used to craft over 40 fires, whittle several spoons, and beat on for yard work. The sheath is incredible quality. I would carry this knife every day if I didn't get strange looks in public. Simply a purpose built tool that will last several lifetimes and well worth the price, especially compared to some other manufacturers. So good I had to order an ursus cub for a bit more of a discreet carry for day to day, but the ursus 45 will be with me on every outdoor adventure.

    Workhorse Extraordinaire

    Posted by Dano Boreman on Apr 8th 2024

    I had been searching for a knife that could do it all. The day the Ursus 45 arrived, my search ended. Everything about this knife fits the bill. Is it pricey? Yes. Is it worth every penny? Absolutely. This is a knife that could be handed down to your kids. Do yourself a favor and take the plunge. You won't regret it.

    Can not explain how impressed with this product I am. Everything claims to be arrived on time and before I opened the box I knew it would be. Just the care that was taken on the tape of the box told me this was going to be a well made product! Been looking for the “bushcrcat” knife I would carry bought several now and this is the one!!

    Fit and a finish is wonderful. Feels solid and well balanced. The handle grips just right. The sheath is a nice positive snug fit and locks the knife in place but still provides easy removal. Can't be more happy with this purchase.

    This knife is so very capable around camp and while traveling through he wilderness. Strong and stout are works that come to mind. Useful for firecraft, camp craft, anything you could need such a tool for, this knife will deliver and remain in good condition whatever abuse you heap upon it.

    My go to knife

    Posted by Jeramiah on Aug 3rd 2023

    I am building a cabin in the Mark Twain national Forest. This knife has turned into my go to knife. I use it all day every day from being a chisel to carving notches in the logs digging slivers out whatever I put in front of it this knife works amazing. And it holds an edge. I love this knife. I have the Kydex sheath and the leather sheath. I prefer the leather but I have cut through the sheath a few times putting it away.

    The knife is amazing I have only recently bought but have already field-tested it and am surprised that it's not much more popular with bushcrafters.

    URSUS 45

    Posted by Samuel on Apr 17th 2023

    I feel like this knife is the progeny of the American flag @#$%&?! an Abrams tank. Instant classic workhorse for me, wether it’s batoning, (minor ) chopping, whittling, or wearing around the house to get my sweet lady in the mood ( ok l, maybe not that last part ) This a strong, durable, handsome knife that will treat you right. Love this knife, and would recommend it to anyone except my neighbor Frank, he sucks

    Amazing comfort in hand

    Posted by Michael Lingard on Apr 5th 2023

    I have the Ursus 45 in 3V steel and black burlap micarta. I honestly can't say enough about how much I like this knife. It is easily the most comfortable knife in the hand that I own... And I have a lot of knives. I can make fire tinder and feather sticks all day long with this thing with no discomfort. The kydex sheath is perfect, and has excellent retention. The micarta looks amazing, but I love how it's finished with some texture and not slippery. The Ursus 45 is camp knife perfection in my opinion.
