About the White River Ursus Series
The White River Ursus series is the heavy-duty outdoor platform in the White River Knife and Tool lineup, built for buyers who want more blade, more spine, and more capability than the M1 and Firecraft platforms. The name Ursus is Latin for bear, and the design reflects that: thicker stock, a taller blade profile, and a geometry that handles wood processing, food prep, shelter building, and sustained field tasks without complaint. Every White River Ursus knife is made in Michigan from CPM MagnaCut steel at 63-64 HRC, includes a flat-ground ferro rod spine for fire starting, and ships with a Kydex sheath and ferro rod included. GearJunkie named the Ursus 45 the best bushcraft fixed blade they had tested, calling it the Platonic Form of a fixed blade. For buyers shopping the white river ursus for sale, both the Ursus 45 and Ursus Cub are in stock and ready to ship.
White River Ursus 45
The White River Ursus 45 is the full-size platform in the series. The blade is 4.5 inches, overall length is 9.5 inches, blade thickness is 0.158 inches, and the weight is 8.3 oz. The drop point blade in CPM MagnaCut at 63-64 HRC gives you the best currently available combination of edge retention, toughness, and corrosion resistance in a production bushcraft knife. The spine is ground flat at the top to strike a ferro rod cleanly, and the Micarta handle is contoured with fore and aft guards that keep the hand secure through hard use. Handle options include black burlap, natural burlap, and black/OD linen Micarta. Each Ursus 45 knife ships with a Kydex swivel loop sheath and a matching ferro rod. This is the knife for buyers who want one tool to handle firewood processing, food prep, shelter work, and sustained camp tasks without compromise.
White River Ursus 45 MagnaCut vs S35VN
White River currently ships the Ursus 45 standard in CPM MagnaCut. Earlier production runs used CPM S35VN, and some S35VN configurations may still be available. MagnaCut is the upgrade: it outperforms S35VN in edge retention, corrosion resistance, and toughness at the same hardness range, which is why White River moved to it across the Ursus lineup. The white river ursus 45 magnacut is what we stock and what we recommend. If you specifically want an S35VN configuration, give us a call, and we can check current availability.
Why the White River Ursus
The Ursus series competes directly with the best bushcraft fixed blades from any maker at any price point. The combination of CPM MagnaCut steel, a properly ground ferro rod spine, full-tang construction, quality Micarta handles, and a sheath system that actually works in the field is difficult to match in American-made production knives. GearJunkie called the Ursus 45 the best bushcraft knife they had tested after years of recommending the LT Wright GNS as their top pick. We have been selling White River knives since the early days of the brand and recommend the Ursus series without hesitation to anyone who wants a serious outdoor fixed blade built in the United States.
Frequently Asked Questions
What is the difference between the Ursus 45 and the Ursus Cub?
The White River Ursus 45 has a 4.5-inch blade, 9.5 inches overall, and weighs 8.3 oz. It is sized for heavy outdoor tasks including batoning, shelter building, and sustained field work. The White River Ursus Cub is shorter and lighter, suited to everyday carry, food prep, and lighter bushcraft tasks. Both use the same CPM MagnaCut steel, ferro rod spine, Micarta handles, and Kydex sheath with ferro rod included. The choice comes down to how much blade you want to carry.
Does the White River Ursus come with a sheath?
Yes. Every White River Ursus knife ships with a Kydex swivel loop sheath and a ferro rod. The sheath is custom molded to the knife, has multiple mounting locations, and is built for field carry. The ferro rod is matched to the flat-ground spine of the blade for reliable spark production.
What steel is the White River Ursus made from?
Current production White River Ursus knives use CPM MagnaCut steel at 63-64 HRC. Earlier models used CPM S35VN. MagnaCut is the better performing steel and is what KnifeArt stocks. Both are American-made particle metallurgy steels with outstanding performance for bushcraft and outdoor use.
Is the White River Ursus good for batoning?
Yes. The Ursus 45 was designed with batoning in mind. The 0.158-inch blade thickness and full-tang construction give it the structural integrity to handle batoning through wood without stress on the blade or handle junction. Multiple buyers have confirmed this in extended outdoor use. The Ursus Cub can handle light batoning but the full-size Ursus 45 is the better tool for sustained wood processing.
