243 Binaka hoe

 The next day, we split into three teams to fulfill Camilo's request.
 Liddy and Helen cut lumber to make the handle of the hoe.
 Samija and Diana work on the sheet metal, and Rike and I make the hoe blade. The quality is, of course, "civilian model".

 Since this is abandoned land, the shape of the hoe will not be a flat hoe, but a b*tc*u hoe - a hoe with four separate tips.
 In the previous world of Japan, it is said to have been invented in the Edo period, but the prototype was made in the Yayoi period, and the iron version in the Kofun period, so it would not be surprising if it existed in this world.

Shall I show you how to make the first one?

 I heat the sheet metal on the fire pit. I feel like I've missed this a lot.
 After the sheet metal is heated, use the iron to make three stripes about two-thirds of the way up, and then roughly shape the sheet metal, making it branch out.
 At this point, the temperature is dropping, so I put it in the fireplace to heat it again, but before that, I show the shape to Rike.

The shape is roughly like this.
"I see.

 Then heat it up to the temperature where it can be processed in the fireplace. The flames from the fire pit sear my face, and I squint and wipe the sweat from my forehead. Still, I keep my eyes on the fireplace.
 When it is just the right temperature, I remove it from the fire pit and place it on the anvil to finish. The hoe also has a blade, so the thinner the blade, the better.
 Since this is a "general model" and we were using cheats, we did not have to make any minor adjustments.
 Once the blade is made, I put it in the fireplace again, this time to work on the other side of the blade. Using a hammer and a sledgehammer, the square part where the handle is attached is processed.
 When that part is finished, the work is not finished .......

You've got the shape.
Is there more?
There's quenching and tempering after this.

 The quenching and tempering process is the same as for any other blade, so I could work on it as if I were familiar with it. I pulled it up when it was just right, feeling the familiar sizzling sound and the cooling sensation on my hand.
 After that, I raised the temperature a little by roasting it over the fire in the fire pit, and it was ready. I inserted the square bar that Liddy and Helen had cut for me, secured it with a wedge, and said, "I'll go try it out.

 Standing beside the field in the courtyard, I raised the hoe, put my hip into it, and thrust it vigorously into the soil. Because the soil was outside the field, it was still unplowed and hard. You can feel its texture in your hands.
 But the hoe is thrusting deeply into the soil.

It is .......

 I dug up the soil with the hoe. I was able to dig up quite deep. When using a flat hoe at this time, it is said that if the soil is hard or clayey, the blade will stick to the soil and make it difficult to work, but with the b*tc*u hoe, the soil will not stick and it will be easy to work.
 However, working while sitting in the middle is quite hard on the back, even for a man in his thirties. In the previous world, the b*tc*u hoe with a step stool was invented in the Taisho era, and it is said that you can work standing up with it.

Is that enough?

 I thumped my back and carried the hoe back to the workshop.
