The strength of the test should be equal to that of the other two. It is not necessary to commemorate the fact that the violence test is stronger than the other one, because there are uncertainties in the limit test, and the results can not be 100% accurate. In reality, no matter law enforcement or self-defense, the stick will hardly be bent. Both of them have no problem opening bricks, the quality is excellent, but Eka wins in the internal components. Eka is an international high-end product after all. it is very smooth to produce sticks. like a resistance stick, it has almost zero resistance all the way, and it can reach the level of lock stick without using force to throw it. gas can't match this point at all. after all, the cost is there. But Eka feels like it's not as good as gas. It's too thick for Asians. After all, German things are mainly about the body shape of Europeans. If you hold it in your hand, you will find that gas holds it more sensibly. I prefer Eka if it's not good for either of them. After all, it's the kingdom to use convenience on the basis of good quality. But is the cost-effective ratio, gas enough, quality not to say, a lot of bricks have been opened, besides a little paint, what else is the problem.
