Its a great thought indeed to gift VK to your dear ones.
I have given VK to my dear ones who are just wearing and i see many changes in their lives.
Using VK to charge water or send energies, are few of the methods. But as you know VK is an intentional tool and follows clear positive thoughts and desires of the user/wearer. Its always helpful.
Do not restrict in your mind that how will he benefit. Just request your VK to make way that he gets aligned with his VK. I have done this all the times.
Just wearing VK, boosts our aura and has effects on our energy systems too. VK sends continuous energies to the person who wears it.
Forum is there for all VK users, we will guide him whenever he wants to learn. Also there is lot of information on litairian website to learn, So that would be easy for him too.
