I am looking a something with rubber handle (I forget the brand name) ... but no decisions yet I am wondering if carving rock maple is going to be more than I want to undertake, so am looking at other woods too. maybe something a bit softer.
The best thing I have found in taking away hard materials is a circular chainsaw that fits to a grinder. I would have to pull it out and have a look but I think it was made by King Arthur. When you set it correctly you can take some really fine cuts with it and it leaves very little to do with hand tools.
Just a thought and I hope it helps.
For hard carving or just removing a lot of wood, the Foredom is a really good machine! I mainly use knives but when I need it I use the Foredom and they also have an amazing variety of bits/burrs. The dremel, which I have also, I just use for small, light jobs...I don't think the Dremel would do you much good on rock maple! You probably would burn it up. imho
