Hi Rajinder
No, if you can't sharpen them then they won't wear very quickly.
You've been the victim of low-cost manufacture. The best solution is
to use an angle grinder, with care not to overheat and draw the temper
of the tines. An engineering shop might help

Wrong way round, rRobert - you temper steel by making it softer.

Tempering reduces hardness but increases ductility and toughness.

Toughness up to a point - the point being reached at around dark blue,
after which it becomes more ductile, but a bend in its structure will
break some of the grain, leading to eventual fatigue failure.
