Digging fork recomendations please

I use a wooden shafted stainless steel boarder fork for loosening the soil I also have a larger wooden shafted garden fork which I used when I did heavy digging, found a fork better than a spade, I also bought a long wooden shafted stainless steel fork out of lidels but the metal is to soft and some tines bent when trying to lever out boulders but still in use when required to lever up heavy objects the long shaft makes the work that bit easier
