Blade Anatomy

9 terms

Blade

The primary metal component of the knife used for cutting, extending from the tip to the ricasso or guard.

Blade Tip

The forward-most point of the blade where the spine and cutting edge converge.

Spine

The unsharpened top edge of the blade, opposite the cutting edge, often thicker for strength.

Cutting Edge

The sharpened portion of the blade that runs from the heel to the tip, used for cutting.

Heel

The rear-most portion of the cutting edge, located closest to the handle.

Ricasso

The flat, unsharpened section of the blade just above the guard or handle, often used for the maker's mark.

Fuller

A groove or channel ground into the side of the blade to reduce weight while maintaining strength; often mistaken for a "blood groove."

Choyle

A small, rounded notch cut into the blade just forward of the ricasso, often used to ease sharpening of the full edge.

Bevel

The angled surface ground into the blade to create the cutting edge.

Grinds & Edge Details

5 terms

Plunge Grind

The point where the grind of the blade's edge bevel begins, forming a distinct notch or transition near the ricasso.

Hollow Grind

A blade grind featuring a concave bevel, producing a thin, sharp edge often seen on skinning knives.

Convex Grind

A blade grind with a gently curved, outward-bulging bevel that tapers smoothly to the edge, prized for strength and durability.

Swedge

An unsharpened, false-edge-like bevel ground into the spine near the tip to reduce weight and improve penetration without adding a functional edge.

False Edge

A sharpened or edge-like bevel on the spine near the tip that resembles a second cutting edge, sometimes actually sharpened.

SEC. III

Handle & Tang

9 terms

Guard

A crosspiece situated between the blade and the handle that protects the user's hand from sliding onto the edge.

Quillion

A finger guard or extension, often part of the guard, that curves toward the blade to protect the hand or assist in retention.

Handle

The part of the knife gripped by the hand, typically covering or attached to the tang.

Handle Scales

The two panels of material (wood, bone, G10, etc.) attached to either side of the tang to form the handle.

Tang

The rear extension of the blade steel that runs into the handle, providing structural support and a base for attachment.

Full Tang

A tang that extends the entire length and width of the handle, typically visible along the edges of the handle scales.

Hidden Tang

A tang that is narrower than the handle and fully enclosed within it, not visible from the outside.

Through Tang

A tang that extends completely through the handle, often visible or peened at the butt end.

Butt Plate

A cap or plate fixed to the rear end (butt) of the handle, protecting the tang end and often used for added durability or striking.
