There is nothing wrong with holding a sickle in your left hand. There is a saying that people with sickles in their left hands are generally a little clever. Because your left brain dominates the action of your left hand, its intelligence is lower. If you use it, you will be smarter than people who do things with their right hands, because everyone develops only the right brain ability with their right hands, so others say that people who use their left hands are smarter.
