Welcome to SRP!

Lots of good advice already. Different grinds are just that. They don't generally serve different purposes from a shaving point of view, and as a general rule there are no "finishing" or "initial" razors, although there's nothing wrong with that idea I suppose.

The Bengalls are excellent shavers, as long as there is nothing structurally wrong with them. You will find them everywhere in Aus., and they are a stand-up razor by any standard.

Looks like you have plenty of excellent offers of help already, so I will just close off by saying welcome again and good luck. If we can do anything, help is just a PM away!

James.
