It takes time to sharpen the knife, but it doesn't delay cutting wood. It means that if you make full preparations in advance, you can speed up your work.
Ade and Acai went up the mountain to cut firewood together.
You must go to bed early and get up early when you go to the mountain to cut firewood, so that you can reach the firewood cutting site at dawn. Ade thought, "If you cut one more bundle, you will get more income. I will get up earlier tomorrow and arrive before dawn." After returning home, Acai took the time to sharpen his knife and prepared to knife stone Take it up the mountain. 
Sharpening your ax will not delay your job of cutting wood Ade rejected Acai and thought, "I don't want to waste time. I can cut more firewood while you are resting."
Soon the day was over again. Ade only cut six bundles of firewood, while Acai picked some wild hawthorn to amuse the children in addition to the nine bundles of firewood he cut.
Adebaisi couldn't understand why he worked so hard, but he didn't cut as much as Acai.
On the third day, Ade tried to cut down trees while observing the work of Acai. He could not see the secret of Acai, but he cut fast. Finally, Ade could no longer help asking, "I have been working hard, and I don't even have time to rest. Why do you cut more and faster than I do?"
Acai looked at him and said with a smile, "In addition to skill and strength, what is more important is the axe in our hands. I often sharpen my knife, and the blade is sharp, so of course, I cut more wood. But you never sharpen your knife. Although it may take more effort than I do, the axe is getting dull, and of course, there is less wood to cut." [1]
