As the shafts are hardened, they are very difficult to cut (i.e. you will not be able to use a hacksaw, etc to cut). If you do need to cut, use either a lathe with a tungsten carbide cutter, a specialized saw (i.e. brobo), or a grinder (not recommended as the heat produced from the grinder affects the shaft hardening). So basically it is highly recommended to buy the length you need as it is a b**ch to cut.
