If you want to use your cutlery classically, then there are two ways you can proceed- American style and European or continental style. However, the positioning of the knife remains the same in both styles. You can use it while cutting the food. Hold it in your right hand. Now, rest the index finger near the base and wrap the other four fingers around the handle. If you are left-handed, then you can consider reversing almost everything. So, that depends on you.
