Welcome Ruvane
You've asked a question that I am sure you will get a hundred different answers to.
I am in complete agreement that you need to purchase a kevlar, or some other type of protective glove though. It takes a bit of getting use to, but if you start out right, you will never regret it. I cut right through my thumb guard when I started. Leather just doesn't hold up.
The other important item to purchase is a hard Arkansas sharpening stone. Nothing will cut you faster than a dull tool. Besides I found that if you try to carve with a dull tool, it takes away much of the joy as you work harder for ugly ragged cuts.
So far as your next 'tool', I would recommend some sort of palm tool. Flexcut has a palm tool handle with interchangable gouges and v-tools that might work out pretty good. It is difficult to suggest only one as I use all of mine because they each serve different needs. If you prefer individual tools, Ramelson makes some good quality, inexpensive palm tools.
You should talk to
Rick@littleshavers.com. His number is on his website. He helped me get started and is an awesome resource.
Good luck to you and welcome.
