May have to try badger's idea. 
I typically split out a stave with wedges.  If it's a sapling, skip that part. 
I tend to use a hatchet to get rough diminsions, along with a drawknife.
Following that I use a series of rasps and knife scrapers to chase a ring if I need to.  Not always. 
Most of the final shaping and early tillering I do with rasps and maybe a knife.
Final tillering has been done with assorted rasps.  Now I'm trying out a knife scraper.  See how that goes. 
Sandpaper to finish off.
