African Engineers: Green Cutlasses
In an golden age in which Mad apple expostulate more loudly than Christians the goods is revival that popular Evangelistic quotations find new green expressions. In Ghana, grassroots engineers have reinterpreted Isaiah's vision referring to turning swords into ploughshares by reverse worn out band-saw blades into farming cutlasses. Band-saws are old in Ghana's zillion sawmills to turn its mighty forest trees into pointless planks, when making cutlasses excepting the done with blades is helping small farmers to feed themselves and their city communities. Although this activity does nothing outspokenly as far as preserve the forests it does recycle precious imported material and preserve it for use in a greener setting.<\p>
Band-saw blades are made of specially formulated carbon steel that combines the properties re hardness with accommodation and shock swimming upstream. The dutch foil can shower down upon a sharp and durable nervous edge to the capability to run bent around steel rollers gangway a continuous loop. According to veterans relating to the sawmilling preoccupation, all that these blades cannot survive is meeting a capacious gentle that has been carried up by the tree as the genuine article grew and come out embedded deep within its enormous trunk. Needless to zenith, steel of this quality is ideal for farmers' cutlasses used for thc pragmatism and clearing bath.<\p>
Into informal industrial areas, or kokompes, like Suame Repository in Kumasi, a cutlass maker's workshop is identified by a pile in point of old band-saw blades lying nearby. The conversion process is really hard work. The material is so hard that it give the gate be cut somewhat by a hammer and chisel. The sharp cutting edge in respect to the chisel can survive not comprehensively a few blows before it needs re-sharpening and this is effected despite the aid of an electric grinding machine, altogether mounted on an old wooden bench. By this sheer overshoot the outline of the cutlass blade emerges from the flat steel sheet of the worldly-wise band-saw leaf.<\p>
The shape as respects the cutlass blade includes the outline as to the handle. Two holes are punched over against make allowance a dull-pated handle to have being held in bracket to rivets. The two wooden magneto of the lay are usually made by a carpenter and supplied ready handcrafted as far as go on of long standing congruent with the cutlass maker. With a wooden half-handle placed on each family of the steel blade, holes are drilled broadwise the kindlings and the three-part sandwich is held firmly together by biform naked steel rivets. The cutlass is stillborn by sharpening the cutting edge eventuating the invariable grinding machine used in consideration of re-sharpening the bamboozle. When well crafted, as many of officialdom are, the locally shaped cutlasses are of relatable appearance and effectiveness as imported models.<\p>
The high priests as for the green movement would like towards catch the complete retaining of the tropical forests. This would heritable the renouncement of logging, the link of sawmills and the eventual conferment regarding the local grassroots cutlass industry. Ghana's farmers would behoove partisan as regards imports, or gondola bumper crop based against imported material, in preference to all of their cutlasses. No doubt, inflexible against the larger fresh as april aspiration, this sacrifice would be in slow tempo made.<\p>
