Plastic. Plastic is easy to manufacture and process, and therefore inexpensive; at the same time, it is lightweight and can have almost any shape and colour. The durability rating of plastic is average, but an explicit con is the tendency of scratches, and with strong impacts — cracks. As a result, this material is used mainly in inexpensive models of pens of everyday use and school-student purposes.
—
Metal. This material can be attributed to the premium class. The metal is durable, reliable, easily endures heavy loads (such a handle will bend rather than break), while it has a stylish and respectable look, and is also pleasant to touch. It weighs significantly more than plastic, but in this case it can be called a virtue — "weightiness" enhances the impression of respectability and reliability. The main disadvantage of metal is its high cost.
—
Carbon. Composite material in the form of carbon fiber, supplemented with plastic filler. With a low weight, this combination is characterized by extremely high strength (often higher than that of steel), and also looks good due to the specific pattern on a dark surface. The main disadvantage of this material is the high price, while the mentioned pros for pens are not required in most cases. As a result, carbon is rarely used — in some high-end pens (and not for practical, but primarily for aesthetic reasons)
....
— Rubber. In this case, we mean a solid body (usually metal) with an additional coating of rubber or other similar material. Soft and resilient coating makes the pen more comfortable to hold, reduces fatigue of writing, moreover, most types of rubber do not slip even with wet fingers. On the other hand, such an addition increases the weight and thickness of the handle, which is not always desirable, and also affects the cost. Therefore, rubber body have not received spread retail.
— Leather. Solid body coated with genuine leather or leatherette. Such a coating performs mainly an aesthetic function, giving the pen a respectable appearance. Among cons, leather is expensive, and leatherette are prone to fraying and cracking with deterioration. Therefore, this option is extremely rare.
