Hacksaw blade

Flexible blades – have only the teeth hardened and are recommended for use where the work cannot be held firmly or is in an awkward position.
All hard blades – hardened throughout, use for sawing hard or tough metals. Their rigidity helps in accurate sawing and they will last longer than flexible blades. However, they will shatter if used incorrectly.
