KNIVES and BLADES

Today my topic is knives and blades. I think it is the most common instruments that used by all of us in our daily life. Before going to discuss this topic, I know what you think these two instruments are the most common and everyone known about how to use them. But this topic contain a broad range of blades and knives that used in in kitchen, medical field, crafting and painting, and specially I mention some name that used as a weapon in human history for war.

SURGICAL BLADES

Surgical blades, or scalpels, are used for cutting skin and tissue during surgical procedures. There are different types of blades specific to the type of procedure. Surgical blades vary by size and shape. The number of the blade indicates the blade size and shape. Surgical blades are typically made with stainless steel or carbon steel.

Surgical blades come in a variety of forms giving surgeons and medical staff the right blade for the procedure. Surgical blades are typically sold separate from the blade handle. Surgical blades are available in disposable scalpels (sterile and non-sterile). Disposable scalpels are single-use scalpels that commonly use a plastic handle connected to a surgical blade. Safety scalpels are scalpels that have a covering around the blade that covers the blade until it is used. Safety scalpels help prevent accidental contact with the surgical blade.

Some of the most common blades are described below:

The number 10 blade has a large curved cutting edge is one of the more traditional blade shapes and is used for making large incisions and cutting soft tissue.

The number 11 blade is an elongated, triangular blade sharpened along the hypotenuse edge. It has a pointed tip making it ideal for stab incisions and precise short cuts in shallow recessed areas.

The number 12 blade is a small, pointed crescent-shaped blade sharpened along the inside edge of the curve. It sometimes used as a suture cutter.

The number 15 blade has a small, curved cutting edge ideal for making short, precise incisions.

The number 22 blade is a larger version of the number 10 blade with a curved cutting edge and a flat, unsharpened back edge. It is often used for creating large incisions through thick skin.

The distinguishing factors of a surgical blade are the edge, spine, and slot.

The edge of the scalpel blade is the sharp cutting surface. Scalpel blades are available in a variety of different styles. The main differences relate to the overall size of the blade or the shape of the cutting edge.

The spine of the scalpel blade is the unsharpened, rigid edge. Scalpel blades are generally made of hardened and tempered steel, stainless steel, or high carbon steel.

The most common type of scalpel blade used in surgery is the non-attached, replaceable blade. This type of blade has a key-like slot at the angled base that securely locks the scalpel blade to the scalpel handle. The scalpel handle is “armed” or “disarmed” by sliding the end of the handle in or out of the slot.

SCALPEL

A scalpel, or lancet, or bistoury, is a small and extremely sharp bladed instrument used for surgery, anatomical dissection, podiatry and various arts and crafts (called a hobby knife). Scalpels may be single-use disposable or re-usable. Re-usable scalpels can have permanently attached blades that can be sharpened or, more commonly, removable single-use blades. Disposable scalpels usually have a plastic handle with an extensible blade (like a utility knife) and are used once, then the entire instrument is discarded. Scalpel blades are usually individually packed in sterile pouches but are also offered non-sterile. Double-edged scalpels are referred to as "lancets".

Scalpel blades are usually made of hardened and tempered steel, stainless steel, or high carbon steel; in addition, titanium, ceramic, diamond and even obsidian knives are not uncommon. For example, when performing surgery under MRI guidance, steel blades are unusable (the blades would be drawn to the magnets, or may cause image artifacts). Historically, the preferred material for surgical scalpels was silver. Scalpel blades are also offered by some manufacturers with a zirconium nitride–coated edge to improve sharpness and edge retention. Others manufacture blades that are polymer-coated to enhance lubricity during a cut. Alternatives to scalpels in surgical applications include electrocautery and lasers.

ART KNIVES

Art knives come primarily in two types:

- palette knife resembling a putty knife with a rounded tip, suited for mixing paints on the palette;

- painting knife with a pointed tip, lowered or "cranked" like a trowel, suited to painting on canvas.

PAINTING KNIVES

A painting knife is an artist's tool with a flexible steel blade used to apply paint to the canvas.

It has a pointed tip, lowered or "cranked" like a trowel, suited for painting on canvas. The blade can be of different lengths and shapes : triangular, rectangular or more diamond like.

A painting knife is different from a palette knife which has a straight wide blade and a rounded tip, better suited for mixing paints on the palette.

PALETTE KNIVES

A palette knife is a blunt tool used for mixing or applying paint, with a flexible steel blade. It is primarily used for mixing paint colors, paste, etc., or for marbling, decorative endpapers, etc. The "palette" in the name is a reference to an artist's palette which is used for mixing oil paint and acrylic paints.

palette knives are manufactured without sharpened cutting edges, with prolonged use they may become "sharpened" by the action of abrasive pigments such as earth colors.

Palette knives are also used in cooking, where their flexibility allows them to easily slide underneath pastries or other items.

UTILITY KNIVES

A utility knife, sometimes generically called a Stanley knife, is a knife used for general or utility purposes. The utility knife was originally a fixed blade knife with a cutting edge suitable for general work such as cutting hides and cordage, scraping hides, butchering animals, cleaning fish, and other tasks. Craft knives are tools mostly used for crafts. Today, the term "utility knife" also includes small folding or retractable-blade knives suited for use in the general workplace or in the construction industry.There is also a utility knife for kitchen use, which is between a chef's knife and paring knife in size.

Chef's knives

In cooking, a chef's knife, also known as a cook's knife, is a cutting tool used in food preparation. The chef's knife was originally designed primarily to slice and disjoint large cuts of beef. Today it is the primary general-utility knife for most western cooks.

A chef's knife generally has a blade eight inches (20 centimeters) in length and 1 1⁄2 inches (3.8 cm) in width, although individual models range from 6 to 14 inches (15 to 36 centimetres) in length. There are two common types of blade shape in western chef's knives, French and German. German-style knives are more deeply and continuously curved along the whole cutting edge; the French style has an edge that is straighter until the end and then curves up to the tip.

BLADED WEAPONS

There are a great variety of knives throughout the world and throughout history, including edged weapons in Asia and Africa, from the jambiya of the Middle East to the Indonesian kris. Also consider the decorated daggers of Persia as well as the exquisite knives of Japan, which represent the bladesmith’s finest achievement. From ancient Egyptian flint knives to the rondel and ballock daggers of medieval Europe, and from 17th-century plug bayonets to the classic commando knives of World War II.
