Two points on this.
First, pyrography tools are not necessarily unwieldy. I use the razertip system. The pen is similar in size to a regular pencil, though it does have a cushion grip which makes it easier to handle and keeps your fingers cooler.
Second, writing with one of these is not much like normal writing. In my experience it needs to be done much slower, each part of each letter being done as a seperate stroke. Perhaps more what one call printing.
