A knife may include a blade having first and second blade ends. A blade point may be disposed at the second blade end. A spine may be disposed between the first blade end and the second blade end. A cutting edge may oppose the spine. A primary bevel may be disposed between the spine and the cutting edge. A secondary bevel may be disposed between the primary bevel and the cutting edge. The secondary bevel may include a secondary bevel start line parallel to the spine and along a first longitudinal axis. A ricasso may be positioned at the first blade end adjacent to the cutting edge, the ricasso including a ricasso angle assist bevel. The ricasso angle assist bevel may include a ricasso angle assist bevel start line along a second longitudinal axis, wherein the second longitudinal axis is closer to the spine than the first longitudinal axis.

A blade sharpener for use with a powered rotary tool having a rotatable sharpening element includes a main body having a bore for receiving the powered rotary tool, where the bore extends through the main body along an axis and the main body has a first channel for receiving a blade to be sharpened. The first channel is perpendicular to the rotary axis and opens into the bore to permit a blade to engage the sharpening element. The blade sharpener also includes a guide having a guide channel for receiving a blade to be sharpened where the guide is pivotally attached to the main body to accommodate any curvature of a blade to be sharpened as the blade sharpener follows along the blade.

A blade sharpener for manual use includes a base, and at least one sharpening device pivotally attached to the base. Each sharpening device has a channel for receiving a blade to be sharpened. A second pivotally attached device may be sharpening device or a guide. The two devices are pivotable independently of each other thereby accommodating any curvature of a blade to be sharpened as the blade sharpener is moved along the blade.
