For zeny you can set it at conf/char-server.conf, search for: start_zeny
For knife I think it's not possible to give a refined item through the config (unless you give a box) but you can do with script.
Something like:
OnPCLoginEvent: if (!firstLogin) { getitem2 1201,1,1,10,0,0,0,0,0; firstLogin = 1; }end;
I've not tested it but it should work without errors. This will give for a knife for each character on its first login, if you want one per account change firstLogin to #firstLogin
