Sagan was something of an enigma
From the drawing experience and the writing process, a construct of knowledge was built through cooperation between hands on work and abstract theoretical frameworks of creative thinking.
It is sometimes overlooked by tool designers that tools are not always held and operated by bare hands. Gloves are commonly worn for safety and comfort. Safety gloves are seldom bulky, but gloves worn in cold climates may be very heavy, interfering not only with sensory feedback but also with the ability to grasp and hold. The wearing of woollen or leather gloves can add 5 mm to hand thickness and 8 mm to hand breadth at the thumb, while heavy mittens can add as much as 25 to 40 mm respectively.

3. Posture is the basis of skilled movements and visual observation. Many tasks require fine, skilled hand movements and close observation of the object of the work. In such cases, posture becomes the platform of these actions. Attention is directed to the task, and the postural elements are enlisted to support the tasks: the posture becomes motionless, the mus-cular load increases and becomes more static. A French research group showed in their classical study that immobility and musculoskeletal load increased when the rate of work increased (Teiger, Laville and Duraffourg 1974).
Back strains and sprains and more serious problems involving the intervertebral discs are common examples of workplace injuries that can be avoided. These often occur because of a sudden particular overload, but may also reflect the exertion of excessive forces by the body over many years: problems may occur suddenly or may take time to develop. An example of a problem that develops over time is seamstresss finger. A recent description describes the hands of a woman who, after 28 years of work in a clothing factory, as well as sewing in her spare time, developed hardened thickened skin and an inability to flex her fingers (Poole 1993). (Specifically, she suffered from a flexion deformity of the right index finger, prominent Heberdens nodes on the index finger and thumb of the right hand, and a prominent callosity on the right middle finger due to constant friction from the scissors.) X-ray films of her hands showed severe degenerative changes in the outermost joints of her right index and middle fingers, with loss of joint space, articular sclerosis (hardening of tissue), osteophytes (bony growths at the joint) and bone cysts.

The polishing process is based on grinding the fixed rough diamond over diamond dust bonded to the polishing disks surface. Owing to its hardness, only grinding by friction against similar carbon material is effective in manipulating the diamonds shape to its geometric and brilliant finish. The workstation hardware is composed of two basic groups of elements: workstation mechanisms and hand-held tools. The first group includes an electric motor, which rotates a polishing disk on a vertical cylindrical shaft, perhaps by a single direct drive; a solid flat table which surrounds the polishing disk; a bench seat and a source of light. The hand-held operating tools consist of a diamond holder (or tang) which houses the rough stone during all polishing phases and is usually held in the left palm. The work is magnified with a convex lens which is held between the first, second and third fingers of the right hand and viewed with the left eye. This method of operation is imposed by a strict training process which in most cases does not take handedness into account. During work the polisher assumes a reclining posture, pressing the holder to the grinding disk. This posture requires the support of the arms on the working table in order to stabilize the hands. As a result, the ulnar nerve is vulnerable to external lesions due to its anatomical position. Such an injury is common among diamond polishers and has been accepted as an occupational disease since the 1950s. The number of polishers worldwide today is around 450,000, of whom approximately 75% are located in the Far East, primarily India, which has dramatically expanded its diamond industry in the last two decades. The act of polishing is done manually, with each of the diamond facets being produced by polishers who are trained and skilled with respect to a certain part of the stones geometry. The polishers are a clear majority of the diamond craft force, composing about 80% of the overall industrys workforce. Therefore, most of the occupational risks of this industry can be addressed through improving the operation of the diamond polishing workstation.
