When sharpening the knife, hold the handle firmly with your right hand, hold the blade lightly with your left finger, and move it clockwise. The surface of the whetstone should be kept moist. The blade surface and the sharpening stone surface should maintain a stable and constant angle. Stone debris on the blade surface will remind you of the corresponding angle.

When he entered the village fast, it was strange that instead of going home as usual, he went to the east of the village and deliberately hit the door of the rich man and passed by. It turned out that he was trying to attract the greed of the rich man, and his evil thoughts flowed. Sure enough, the rich man immediately asked:

"Agudumba, look at this bitch full of you, what is it?"

"Grain." Aguttonba answered simply.

"Yo, you're not easy! Where did you get it?"

"There is no way to be poor, so I have to make a small sale! Yesterday, I brought a bit of whetstone to Lhasa. This grain was exchanged for the whetstone."

The rich man heard that "a little bit of whetstone" was exchanged for so much grain, and felt that it was a way to make money, which was profitable; so he asked Agudunba in detail about the market situation in Lhasa. Agutumba had already guessed his mind, and gave him a further introduction: "Whetstone is really popular in Lhasa! As soon as I got there, they were snapped up by them. However, in this regard The prices and prices are indeed a bit strange: the large whetstones cost five or two pieces of silver each; the small whetstones sell five or two pieces of silver. This time I was unlucky, and all the whetstones were shipped If it is small, how cost-effective it is! ... The rich man seems to be impatient when he hears this. Maybe he thinks that he wants to inquire about everything already. At this time, he hasn't waited for Aguton. After Ba was introduced, he quickly turned around and shook off Agudun Ba, who was talking, and went back to his dirty life.

That night, he ordered all the servants in his family to smash those whetstones that were already available and suitable. Facing these small rocks piled up, the confused rich man's wife couldn't help wondering:

"You're crazy. Why would a good whetstone smash it like this?"

"You know the fart! When you arrive in Lhasa tomorrow, you will know!" Said the rich man with an arrogant expression, and his face was filled with a contented and very mysterious smile.

In the early morning of the next day, the rich man went out himself, leading a long, gang with a small whetstone smashed, and marched towards Lhasa. Upon arriving in Lhasa, it really attracted many "customers". But when people saw that the net was small and indestructible small stones, they became a visitor, and the rich man's sharpening stone was placed for a whole day, and he did not even sell one. go with.

Later, he knew he had been fooled, and hurried back to find Agudunba to "settle accounts" and questioned:

"You said whetstone is very fragrant. I shipped it. Why didn't I buy one?"

Agutton Bally replied bluntly:

"Everyone bought me yesterday. Why did they buy you just overnight? Whetstone cannot be eaten for dinner!"
