1. Don't hit people with the first shovel. The first shovel must be a knife. Just touch it and get rid of the watermelon knife.

2, the shovel can control the damage, and if you want to die and be disabled, you can cut it directly. If you just want to subdue your opponent, you can shoot with a shovel. This is something that watermelon knives can't do.

PS: It was the German storm commandos who first put forward the use of sappers' shovels in melee. They found that sappers' shovels with blades can split, stab and block. If you only hit the other side with a shovel, the other side will basically lose the ability to resist. If you hit the right part, you will die immediately. On the other hand, its equipped daggers and bayonets often stab the other side several times, but the other side can still resist and can only stab. Later, the Germans summed up the experience of commandos in using sappers' shovels in melee, compiled a set of melee teaching materials, and promoted them to the whole army. So during World War II, Germans liked to fight with shovels, but they still used knives. They also received assassination training, but because of their strength, they used shovels more often. During the war, the Soviet army developed a more perfect set of sappers' shovel combat textbooks based on this set of melee textbooks, and used sappers' shovels to deal with bayonets, guns, prisoners and even flying shovels. After the founding of the People's Republic of China, our country also introduced Soviet textbooks, and many older generation soldiers were practicing.
