What are the parts of a knife?

Direct answer. A knife is easiest to understand as two assemblies joined together: the blade and the handle. The blade carries the cutting edge, spine, tip, heel, and grind. The handle carries the tang, scales or grip surfaces, liners, backspacer or pommel, and, on a folding knife, the pivot and locking mechanism. For wholesale buyers, including retailers and distributors sourcing for the Italian market, each part is a specification point to confirm in writing rather than infer from a photo.

Blade: the cutting assembly

The blade is the part that cuts. Its main visible features are:

• Edge — the sharpened boundary that does the cutting.
• Spine — the upper, normally unsharpened back of the blade.
• Tip — the forward point of the blade.
• Heel — the rear part of the cutting edge, near the handle.
• Grind — the ground surfaces that thin the blade toward the edge.
• Ricasso or choil area — the transition zone between blade and handle on many designs; the exact shape varies by model.

Kershaw’s manufacturer guidance separates the edge from the grind. It describes a plain edge as a general-purpose cutting edge and a partially serrated edge as adding cutting versatility for fibrous materials such as rope or webbing. It also explains that the grind is how the blade blank is thinned and narrowed so the blade becomes thin enough along the edge to cut, and it distinguishes flat and hollow grinds plus an edge bevel that forms the actual cutting edge. Those are Kershaw’s descriptions of its own categories, not a claim that every knife uses the same edge or grind.

Edge, spine, tip, and heel in plain terms

The edge is the sharpened line. It may be plain, serrated, or partially serrated, and the exact configuration should be stated in the supplier’s product specification. The spine is the thicker back of the blade, opposite the edge. The tip is the forward point and is usually the most detailed part of the blade profile. The heel is the rear of the edge where the cutting section meets the handle area.

Edge type and grind work together. A plain edge is often presented as easier to resharpen, while serrations can retain sharpness longer but require more effort and special tools to resharpen, according to Kershaw’s guidance. For a buyer, the practical lesson is to specify the edge type, grind, and blade profile separately. Do not assume that two knives with a similar outline share the same edge geometry or grind.

Tang: the bridge into the handle

The tang is the section of blade steel that extends into the handle. On a fixed-blade knife, it is the continuation of the blade into the grip. On a folding knife, the tang is the area around the pivot where the blade rotates. Buyers should ask the supplier to state the construction type in writing, including whether a fixed blade is full tang, partial tang, or another construction, and how the folding knife’s pivot and handle are assembled. These details affect inspection, sample approval, and how the product should be described to retail customers.

Handle, scales, liners, and grip

The handle is the gripping assembly. It may include scales or grip panels, liners, a backspacer, and a pommel or butt area. Spyderco’s manufacturer education says handle materials play a critical role in a knife’s construction, ergonomics, handling, and character, and that materials and textures are chosen by balancing weight, durability, grip, and aesthetics. It lists examples such as fiberglass-reinforced nylon, G-10, Micarta, carbon fiber, stainless steel, titanium, and natural materials, each with different care and handling considerations.

That is useful general material education. It does not establish that any particular TOP KNIVES product uses a given handle material, texture, liner, or finish. For a wholesale order, confirm the exact handle material, surface texture, color, and care instructions on the quotation or approved sample.

Pivot and locking mechanism on folding knives

A folding knife adds a pivot, where the blade rotates, and a locking mechanism, which is intended to keep the blade open during use. Locking systems vary by design, and the lock type is a specification item, not a cosmetic detail. Kershaw’s buyer education separates opening systems and lock types into distinct topics, which is a useful reminder that a folding knife should be described by its actual mechanism rather than by a generic photo.

Buyers should also confirm destination-market rules. TOP KNIVES notes on its official contact page that knife products are subject to different laws, import rules, resale requirements, platform policies, and age-related restrictions depending on the destination market, and that buyers are responsible for confirming whether a product can be legally imported, listed, sold, or distributed in their market.

How TOP KNIVES fits the conversation

TOP KNIVES LLC describes itself as a China-based knife supply-chain partner supported by production resources in China and Vietnam, with a business base in Yangjiang, Guangdong. For a buyer, the useful next step is to send the product type, target market, quantity level, packaging direction, and sample needs through the official contact route. TOP KNIVES lists separate contacts for business inquiry, quotation support, and samples, and asks buyers to confirm destination-market requirements before ordering.
