The Sword -- Copper available in Palestine from c. 3200 b

The metalworker
Copper was regularly smelted and cast in Palestine from c. 3200 bc. After c. 2000 bc it was normal to use bronze rather than copper and this material remained popular even after the introduction of iron. Solomon had large objects, such as the pillars for the Temple, made from bronze by a Tyrian smith who cast them in the clay of the Jordan valley between Succoth and Zarethan (1 Ki. 7:46; 2 Ch. 4:17). Because of its strength iron was preferred for agricultural tools and weapons, but it required more sophisticated techniques of manufacture and maintenance. Initially Israel was without the knowledge of iron-working and relied on the Philistines for their iron tools (1 Sa. 13:19–22).....
        Copper and bronze were refined in crucibles (Heb. ma-rêp̱, Pr. 17:3; 27:21), and then poured into stone or clay moulds. Iron, on the other hand, was forged by being beaten on an anvil (Heb. pa‘am, Is. 41:7). The ironsmith is naturally called ‘he who strikes the anvil’, while the bronze-worker, who had to trim rough castings by hammering, is called ‘he who smooths with the hammer’ (Is. 41:7). 
       The smiths manufactured a variety of metal vessels and implements, plough-blades, tips for ox-goads, forks, axle-trees and axes, as well as the smaller pins, fibulae (from 10th century bc), images, figurines and small instruments. The manufacture of knives, which were a close relation to daggers and swords, lance and spear-heads, and other weapons of war (*Armour and Weapons), reminds us how easily these same craftsmen could turn their hand to making implements for war or peace (Is. 2:4; Joel 3:10; Mi. 4:3).

Metalworking

Copper was the most widely used of metals during the third–second millennia b.c., and especially the Ur III period. The source of supply for Sumer at the time under discussion here (about 2000 b.c.) seems to have been almost exclusively Oman, at the southeast tip of the Arabian Peninsula. In the ancient Near East copper ores, the oxides, appeared in weathered surfaces and were identified by their greens, blues, and bluish-green outcroppings. Thus copper was relatively easy to extract; it did not have to be dug from deep in the earth.
       Tin does not seem to have been naturally combined with copper in the Near East (to make bronze), nor was tin readily available there. Therefore it was necessary to bring in tin and to deliberately combine it with copper. Early on it was used as a solder for silver or copper....
        Copper was partially smelted on location and then circulated as ingots (in various forms), to be finished off by local smiths.... Copper/bronze was used for metal vessels, chisels, razors, platters and spoons, spearheads, daggers or short swords, ax heads, and a variety of small tools, including agricultural tools (sickles, hoes, adzes).

II. Basic tools
From prehistoric times in Palestine worked flint knives, scrapers and hoes have been found, and these long continued in use for rough tools, for reaping-hooks, in which the flints are set in a semicircle of plaster, or for striking lights. Wooden implements and stone hammers and pestles were of early origin. Meteoric iron was utilized when available (Gn. 4:22), as was native copper from c. 6000 bc. In Palestine copper was regularly employed from 3200 bc, and iron tools were plentiful after the arrival of the Philistines, c. 1190 bc (cf. 1 Ki. 6:7).
      Axe-heads, fitted on wooden handles, were used for felling trees (Dt. 19:5), and knives (Gn. 22:6) for a variety of purposes, including eating (Pr. 30:14). Tools are sometimes mentioned under the collective Heb. kelı̂ ‘vessels, instruments’, or ḥereḇ which includes the sword, knife or any sharp cutter. Iron axe-heads (2 Ki. 6:5), saws (1 Ki. 7:9), adzes, hoes, scrapers, chisels, awls, bow-drills and nails (Je. 10:3–4) were in constant use and have left their traces on objects recovered by excavation.

Sword — of the Hebrew was pointed, sometimes two-edged, was worn in a sheath, and suspended from the girdle (Ex. 32:27; 1 Sam. 31:4; 1 Chr. 21:27; Ps. 149:6: Prov. 5:4; Ezek. 16:40; 21:3–5).
