A few situations, let me know your thoughts.
1A - I'm wielding a heavy blaster rifle, can I use it as a Truncheon/Gun Club to make a Melee attack?
1B- How about making an attack with the rifle and following through with a gun-club attack during the same action?
2 - I'm using a long force pike (2 meter model), can I make a Two-Weapon Fighting to attack with both ends?
