Manufactured according to EN 13414-1 and EN 13411-3 , are available in matte, greased matte and galvanised, in different constructions and wire tensile classes, usually 1960. Steel core wire ropes have the core of the same material as the same type of steel cable, which is a wire - and meet the acronym IWRC ( independent wire rope core ) or even steel strand - and meet with the acronym (I)WSC ( (independent) wire strand core ). The steel core presents as the main advantage the higher workload by up to 10% compared to the same wire rope with fiber core, at the cost of increased stiffness.
The minimum upper breaking load is also the main reason why these types of wire ropes are used to make the slings by the method Flemish Eye.
They are available in the galvanised version, with a higher corrosion resistance, with diameters between 6 and 102 mm.
The main constructions available are 6x19S (usually used for small diameters) and 6x36WS.

A flexible and long-life wire rope, the construction of 6x36WS it is used for:
rlitman is correct. Steel core is special and fibre core is standard.
I worked as a rigger in the 70's and 80's and fibre was the most common standard cable you could get. Yours is regular lay, and looks like 6X19 (6 strands of 19 wires) which is the best compromise of strength and flexability. The fibre core holds lubricant. Wire rope is considered a machine. Each wire in the rope is preformed to a specific spiral shape with slight flats spots so it nests together with the other wires to form the strands which form the rope and these wires move under load or around bends to share the load. The fibre core has some give and holds the lubricant needed to keep it friction free.
Steel cores were only used for extra strength. Crane and elevator cable have more outer strands with an inner core wound the opposite direction so it doesn't spin under load. Other cable operated equipment uses Langs lay where the individual wires turn the same direction as the strands so they are very flexible for bending through sheaves.
Logging cables have thicker wires on the out side to resist abrasion and thinner wires on the inside for flexibility. If you look at yours you can see the strands turn to the right but the wires in the strands turn left so they look rather straight. This is "Regular Lay"
We used to splice eyes in the ends or use steel ferrules that we'd pour molten zinc into. Now a days the ferrules are pressed on. You can take your cables into a shop and have them press ferrules on for a reasonable fee. Cable clamps are for guy wires and not working cables. Eye splices are great but too much work and rough on the hands unless you were stuck way out in the bush and had no choice.
1/2" was good for bundling small logs into bundles for booming. Logs under 20" wouldn't stay in a boom in rough weather so they were bundled into 6' round bundles before it went into a boom. We made a simple eye splice called a "Molly Hogan" where you split 3 strands, un wound them and wrapped them back into their own grooves backward. These are best done on site so you can make the length you want.
You should advertise it as is and let the buyer decide how he wants to use it. If you commit it to a specific use you are limiting the market.
