Welcome!!

If you can shave ok with a Shavette you should be good with the real thing. If I remember right the angle on a real straight is lower.

You should probably look at getting a +8k hone or CrOx pasted paddle for edge maintaining on a shave ready razor. If you are looking at antique store/ebay restoring you will need more hones (1k,4k,8k or similar to start with)
