The **SOG One-Zero XR** is a robust pocket knife for everyday use. As SOG states: 'Made for those that demand quality and precision.' The One-Zero certainly lives up to that. It's a high-quality knife. A lot of attention has been paid to details that many knife brands do not bother with.

The One-Zero XR is, as the name might suggest, enhanced with the XR-lock. This is a great locking mechanism for both left and right-handed use. The great thing about the XR-mechanism is that the blade slightly sticks from the handle when you pull the lock back. With a slight movement of the wrist you can easily release the blade from the handle. Of course, you can easily open the blade with the thumb hole too, if you prefer.

The handle is made from strong 'aircraft-grade‘ aluminium. The construction of the handle stands out. This one is almost completely screw-free! Only the hinge-screw is visible. The others are hidden away on the inside of the scales. The blade is made from high-quality CRYO CPM S35VN. That means that this steel has been treated with a special CRYO heat treatment. With this, SOG toughens the S35VN steel to meet the high standards they have for their products. The result is a steel that remains sharp for an extra long time, so you'll rarely need to sharpen your knife.

The One-Zero is equipped with a deep-carry pocket clip that allows you to carry it securely in your pocket. It will barely be noticeable that you're even carrying a pocket knife.

General information

We always measure the blade height at the highest part of the blade.

Blade height

We always measure the blade length ourselves. This is the length of the blade from the tip to the front of the handle. This may deviate from the manufacturer's specification.

Blade length

value_blade_length_edge

The length of the cutting edge is measured from the tip to the start of the edge. This may deviate from the manufacturer's specification.

Cutting edge length

We always measure the blade thickness at the thickest part of the blade. Often just before the handle. This may deviate from the manufacturer's specification.

Blade thickness

value_closed_length

We always weigh a product as bare as possible. Knives and axes always without their sheath, lights (if possible) without their battery. For knife sets we measure the entire weight. This may deviate from the manufacturer's specifications.

Weight

Dimensions & weight

value_steel_hardness

The hardness in Rockwell C for a knife is always according to the manufacturer's specifications. When a manufacturer specifies a value of 56-58HRC, for instance, we always note the highest value, i.e. 58HRC.

We measure the sharpening angle ourselves. This value is the angle per side.  So 20º means that the total angle of the edge is 40º. Please note that knives are almost always sharpened by hand, even in factories. This value is therefore only an indication of a single tool measured by us. You are always free to choose your own sharpening angle. [Learn more about sharpening angles](/en/ct/sharpening-angles-explained.htm).

In terms of grind we are talking about how the complete blade thickness extends into the edge. Want to learn more about grinds? [Read all about grinds on knives](/en/ct/knife-grinds.htm).
