Also trusting the application is very difficult to do as well. The fear that it may not work screws up a lot of people. I could teach Jow Ga for free, show that it works, but when it comes to the student's turn to try and use it, There's going to be that fear, and it's a hard one to get over. With weapons, it's going to be even more difficult to master that fear.Without prior MA experience, I think weapons are harder to learn than empty hand, since many empty hand TMA concepts and techniques lend themselves to weapons. With this experience, you have a head start.
If a person is trying to master that fear without a foundation then yeah it's going to be really difficult to learn a weapon in terms of application and functional use.
