Why a drop point

The default hunting and EDC shape, and the safest general answer. The spine curves down to the tip in a convex line, which keeps the point low and strong and leaves plenty of belly for skinning. It is hard to make a drop point bad at anything.

About CPM-S35VN

S30V with niobium swapped in for some vanadium: slightly tougher, noticeably easier to sharpen, marginally less edge retention.

What owners say

Drawn from 171 owner discussions of the White River Ursus 45 since 2024. The opinions are theirs. The specifications above come from the maker.

What owners like

The handle is the standout: one owner calls it the most comfortable knife they have held, another says no knife has ever felt better in their hand, and a third with large-glove hands says it fits nicely.
Game work went well from the first job: one owner dressed out and skinned a coyote with theirs on its first real use and called it outstanding.
It earns its place off the beaten path: one owner who also has a Fallkniven F1 takes the Ursus 45 over it every time and says they have never felt under- or over-knifed with it.
It proves itself in use more than at the counter: an owner of many years says it looks underwhelming and feels meh in a shop but works great in the wild.
The extended finger choil protects the hand: one owner of both knives contrasts it with White River's Camp Cleaver, which nicked them on day one because it is sharp right up to the handle.
The S35VN version is smaller than it looks: one person who handled it found it smaller than they expected but pretty much the perfect size for a camp knife.
Camp cooking is part of its job for one owner, who keeps a smaller Ursus Cub and a Dacian for daily carry and uses the Ursus 45 for cooking on camping trips.

What owners flag

The stock kydex sheath disappointed one owner badly: it rubbed and scratched the blade until they loosened it with a heat gun, the thumb ramp dug in, the dangler backer was thin and flimsy, and the ferro rod holder held the rod upside down.
It can be more knife than you need: one owner bought it as their first camp knife and found it large, heavy and aimed at hard survival use, then bought a White River Hunter that suited their cabin camp better.
Belt carry takes some sorting out at 9.25 in long: one owner found vertical 3 o'clock carry too uncomfortable, and another disliked the dangling belt carry and went looking for scout carry hardware.
The edge is unforgiving when attention slips: one owner shaving kindling with their new Ursus 45 on Christmas cut their index finger badly enough to need 6 stitches.

A coyote skinned on its first outing, camp cooking and trips off the beaten path are what owners use the Ursus 45 for, and its 4.5 in drop point and 8.3 oz build put it in the camp-knife class rather than the everyday belt-knife class. The handle gets the strongest praise: one owner calls it the most comfortable knife they have held, and another has never handled one that felt better.

The most detailed knock is one owner's sheath complaint: they had to heat the kydex to stop it scratching the blade, ground down the thumb ramp, replaced the flimsy dangler, and found the ferro rod holder upside down. Carrying a 9.25 in knife on a belt also takes experimenting, and one owner needed stitches after a slip while making kindling with their new one.

Ursus Cub, Fallkniven F1, LionSteel M5 and TRC South Pole are the knives it gets weighed against. Two large-handed owners prefer it to the Cub, one owner takes it over their F1 every time, and one who only needed a relaxed camp knife moved down to the White River Hunter. This page is the S35VN version; MagnaCut turns up in more recent mentions.

Ursus 45 or Ursus Cub?

Two owners with big hands steer to the 45: one found the Cub's grip too small and carries the 45, and another with large-glove hands fitted aftermarket scales to their Cub while saying the 45 fits nicely. On the other side, one owner found the 45 more than they needed for easygoing cabin camping.

What steel is the Ursus 45 in?

It has been made in more than one. One owner received a 3V Ursus 45, and another handled the S35VN version shown here. In 2026 one knife user recalled the 45 coming in 3V and maybe S35VN, and another said White River has since changed it to MagnaCut, the steel that turns up in more recent mentions.

How do owners carry it?

One owner wears it in the stock kydex dangler on their right hip, while another found vertical 3 o'clock carry uncomfortable and a third wanted scout carry instead of a dangler. One owner bought an Armatus sheath for it, and another reworked the stock kydex sheath themselves.

Ursus 45, LionSteel M5 or TRC South Pole for a long trip?

Opinions were split. Two said to take the Ursus, one said the TRC is by far the most comfortable of the three, and one with 3XL hands preferred the LionSteel's guard and pommel because White River handles do not suit them.
