Over at the One Scythe Revolution  web site, Peak Oil expert Richard Heinberg states that in order to continue to grow the same amount of food in the future, without the use of cheap oil, we will need 40-to-50 million farmers, farming 3-to-50 acres each, cultivated with hand tools. No, not like in the Middle Ages. We are talking about “appropriate technology” here.
But let’s face it, “appropriate technology” is wielded by slaves. Masters wield guns. Slaves wield scythes.
Here is quote: “One good scythe per farm, could revolutionize small-scale farming.” I kinda feel like this has already been done.
I think the author of this tripe has never actually farmed on a large scale and has no sense of the man hours required. Also, mild steel work-hardened with a hammer and honed with slate was state of the art, around the year 900. Carbon steel that can be heat treated has been the cool setup since around 1100 AD. More recent alloys allow even better toughness along with light weight. While the Austrian design may be better, it would still benefit from modern materials.
Then, of course, even 19th Century horse-drawn harvesters were tremendously more efficient :
“Draft horses are used at Grant-Kohrs Ranch NHS to harvest and stack the annual hay crop. The stacks keep the hay preserved until winter when it is fed to the site’s livestock.
The hay harvesting process involves five steps: cutting, drying, raking, gathering, and stacking.
Upon reaching maturity in mid-summer, the hay is cut with a horse drawn mower. The team of horses, mower, and operator go round and round the field cutting a 5 foot swath with each round. Once the cut hay has dried, the draft horses are hooked up to either a side delivery or dump rake. The rakes are used to put the hay into long windrows. The horses are then hooked to a buckrake. The buckrake has fork like teeth that sweep under the windrows and gather them up into large hay piles. The piles are then taken by the buckrake to either an overshot or beaverslide hay stacker. The hay stackers utilize a pulley and cable system powered by horses to gain leverage to lift the hay piles off the ground and drop them into the haystack.
Demonstrations of the equipment used to harvest and stack hay will be given by Grant-Kohrs Ranch staff and horses.”
And other animals can serve for various processes that are presently done with internal combustion engines–such as goats for clearing brush.
As far as forging scythes, without modern powered forges and induction furnace, either one mines coal, or uses every man in the village for a week to do a large scale charcoal burn  to manufacture fuel.

JWR’s Comment: If the Hubbert’s Peak  predictions are right, then the best places to be will be those with rich soil and plentiful hydroelectric power. Scythe? Check. Battle rifle? Check. Electric ATV  that can pull a Plotmaster ? Check. Electric power (with batteries) is not quite as versatile and lightweight as fossil fuel-powered machinery, but it sure beats doing it all by hand.
Perhaps the new rule book will be written by those who can afford horses, harness, horse-drawn hay mowers and enough land to provide sufficient hay for the requisite winter feed (which can be harvested with those same horses).
Only freeholders with both productive farm land and guns will remain free.
