I was wandering, if your spear\'s shaft is made of aluminum, does that have any strength to it, i mean, say you had to block with the shaft, would a weapon break through like your basic sword or basic axe, i don\'t mean big heavy swords and axes, but like average ones, could it break through an aluminum shaft of a spear?From my understanding aluminum weapons are only for exhibitions and never for anything close to real, let alone impact. Aluminum can be a strong/durable metal, but in the end it can hardly hold up against wood like pine, let alone oak. There\'s also here-say about aluminum shattering. I don\'t really know what that\'s about, but I have heard a rumor that about some doing so, whatever the extend of shattering really means. I wouldn\'t bother with aluminum when there\'s very fine woods that can be used instead. Aluminum is also cheap and it\'s said you get what you pay for. Personally, I\'d forget aluminum and go with a hard wood.Why an aluminum spear? Why not a wood spear? A spear needs to be able to take the shock of hard contact against other weapons. If you are thinking that aluminum is lighter therefore faster, then you make a widely held mistake. If tow people of equal skill with a weapon were to face each other, then the one that has greater speed would have some advantage........but that does not mean that he would be the winner. There are many other factors that can determine the outcome. Better timing for one can beat speed. The martial arts are not simple things that can be calculated like math. Besides skills there is luck. None of us can predict that. Put two people against each other... One with an aluminum spear, the other with a wood spear, but better skills, and I\'ll bet on the better trained person. but as I stated, anything can happen due to luck, a mistake (it take only one), conditions. If two people fight and one wins, does that mean that he would always win if they fight over and over? These questions always assume way to many things to be true. Therefore they are flawed questions from the start. ... ...How thick is the shaft? Even if it is solid, if it is fairly thin in order to be light weight like competition weapons I would not bet my life on blocking with something like that. If your shaft is solid and maybe one to 1 1/2 inches thick then maybe. A weapon does not have to be heavy to be powerful. If the practitioner is strong and fast he can generate quite a bit of power even with a lighter weight weapon. A bokken is not very heavy at all but in the hands of a skilled practitioner it can generate enough force to kill. The effectiveness of a weapon is in the technique not the weight. So don\'t underestimate a weapon and let weight fool you.nice question dear.. but strength is depend upon the hardness of material.. if that spear\'s shaft is hollow it can withstand up to certain level only for slow strikes.. but shaft is a rod hopefully i can say block using that even with a basic katana and Axe.. and one more thing your should strike as sparring and for fighting..Other related question
