Says who? It has been used before.
Steel axles are used in most throws, and titanium isnât really stronger than steel, just has a higher strength to weight ratio. The Luftverk Evora Ti7075 uses a titanium axle, and I believe some Yoyorecreation throws have as well. If you donât strip out your yoyos with steel axles, youâll be fine with titanium. Only reason Iâd want it is because it is my âdream designâ, so itâs âUltra Premiumâ, and would save a very minuscule amount of center weight.
thanks!
