Here is some knowledge about work gloves and leather:
Kinds of cuffs:

Now you can get something from this picture below:

All kinds of leather provide comfort, durability, dexterity, mild heat resistance and abrasion protection. These advantages make leather a traditional favorite for industrial workers.

We can measure like this:

The frame of the gloves and the types of work gloves:
Ball & Tape Fastener · Used to snug the fit of a full leather glove at the wrist.
Belly Leather · Leather from the belly portion of an animal hide. Very popular and widely used in full leather gloves.
Binding · Narrow material used to bind the cuff on gloves such as drivers' styles and red lined jerseys.
Bleed · Transfer of dye to the wearer's hands. Not color fast.
Boardy · Stiff, not pliable. A leather description.
Drivers' Glove · Another term for slip on style, full leather glove.
Finger Tips · An added protection and wear feature built into some leather palm glove patterns.
Fleece Lining · Soft, cotton material used for additional warmth and to reduce abrasive chafing in leather gloves.
Flesh Split · The layer of hide next to an animal's muscles and flesh.
Foam Lining · Polyurethane layer, generally covered by fleece or flocked lined with nylon. Makes a good glove lining for warmth.
Fourchette · The sidewall area between the top and bottom of glove fingers made by using additional material.
Forming · Part of the turning process in glove manufacture. Enhances the appearance and straightens seams that otherwise might cause discomfort.
Full First Finger · Wrap around index finger construction that eliminates a seam on the outer finger edge. Longer wear feature.
Full Lining · A glove within a glove, so to speak, as opposed to lining over the back and palm only, leaving the side finger or fourchette areas without lining.
Heel or Continuous Pull · The extended leather portion of a short cuff or gauntlet leather palm glove. For added wear at seam of cuff against constant pulling on.
Keystone Thumb · Type of inset thumb on full leather glove patterns. Provides additional wear and comfort.
Knuckle Strap · A band of leather across the back of a glove covering the knuckle area to provide additional bump and protection.
Lining · The addition of inner materials to provide added warmth or comfort.
Middle Split · A fatty layer between the top grain and flesh split of a cowhide. Looks like flesh split but has no tensile strength or abrasion resistance.
Nap · In fabric gloves. The loose ends of woven fibers that appear fluffy. Nap out on chore gloves, nap in on cotton flannel styles. In leather palm gloves, the loose ends of leather fibers. A nappy appearance indicates poor quality.
Out-Seam-Sewn · Stitching and seams on the outside surface. Seldom used on work gloves because of vulnerability of seams to abrasion.
Pile Lining · Bulky acrylic material used for extra warmth in drivers' gloves.
Roper's Glove · Modified drivers' style. Usually a clute pattern of thin deer, goat or elk top grain leather. Keystone thumbs or english inset thumbs are common.
Rubberized · A term used to describe the bonding of material layers by the use of rubber cement.
Shoulder Split · Suede leather taken from the side of the cow, noted for its strength and durability.
Shirred Wrist · Snugging the wrist by sewing elastic into the wrist area.
Side Split · Sueded leather taken from the side of the cow. Usually more durable and thicker than shoulder split.
Straight Thumb · A glove thumb that normally lies straight up and down. Common to most fabric gloves and drivers' gloves.
Tanning · The process of coloring, softening and adding preservative oils to prepare leather for use in the manufacture of consumer products.
Thermal · Refers to lining. Material woven to trap air and insulate against cold.
Thumb Shield · An extra piece of leather sewn in the thumb to palm seam to add additional wear in this high abrasion area. Found in some drivers' and leather palm styles.
3/4 Back · Used to describe a leather palm style glove who's back is also all leather 3/4 of the way from the finger tips to the wrist.
Top Grain · The outside layer of animal hide, the hair having been chemically removed.
Welder's Glove · Gloves specially made to repel and resist welding sparks. Lined to protect against heat. Usually full leather with gauntlet type cuff which may also be leather.
Welt · Narrow leather strips added to seam areas in stress, heat or abrasion sensitive area. Prolongs wear and adds protection.
Whip Stitch · Sewing method whereby the thread is looped over the outside of the seam. Sometimes used in dress gloves. Almost never seen in work gloves because of the exposure of the thread to abrasion.
Wing Thumb · A type on construction that angles the thumb diagonally across the palm. Frequently found in leather palm gloves. Comfortable.

String Knit Gloves
Dipped Styles
All dipped gloves are created by dipping canvas, interlock, jersey or knitted shells into a polymer such as neoprene, nitrile, PVC, rubber or vinyl - or a combination of these polymers

Types Of Leather
Cow - Cow leather is the most commonly used leather within the glove industry due to its plentiful availability. The United States and Australia produce the majority of these hides. The advantages include comfort, durability, excellent abrasion and breathability. Chrome tanning of this leather provides greater wear and heat resistance.
Pig - Pigskin offers the greatest breathability due to the porous texture of this hide. Additionally, pigskin tends to become softer with use and withstands moisture without stiffening. When laundered, this leather will return more to its natural soft texture than other leathers

Side Split - comes from the rib area of the animal. This part of the leather is more durable and provides the greatest protection because of its greater density of fibers.
Shoulder Split - is more economical than side, but less durable. The additional movement in this shoulder area creates less fibers and a more visable texture difference.
Belly Split - is the most economical; however, it has the least consistency of texture and appearance.
