Weapon training attributes to empty hand

Can weapon training attributes be transferred to empty hand fighting?

Some principles, attributes, and techniques from swords and machete transfers nicely into empty hands BUT some do not.
We have to be very careful not to generalize too much. Often people might say that it all transfers, BUT upon closer examination, it does not.

Like all things , there is a universal aspect to it and there is also a unique aspect to it.
Universal is transferrable, Unique is not. Yin and Yang. Everything is Yin and Yang… that’s Tao.
