I am planning to use this knife to shave wood for starting fires and cut up fuel for my Bushbuddy stove. Overall I love this knife with it's nice grip.

I wouldn't run right out and buy another knife, but all-in-all, I prefer a plain blade. As others said, a serrated knife is better for cutting rope and fiber, but a plain blade is so much easier to sharpen and as a general use tool. Spyderco does turn out a good product and you can depend on it.
I just got a Boker Trance knife and I like it a lot. It would fit your needs well and they can be found for under $30. A mora would make a nice lightweight and inexpensive companion for your current knife. Another alternative might be to consider a small saw like the Gerber Sport Saw– just a few ounces and will cut your stove wood quickly.
The best alternative is not the lightest. If you want to split wood using a baton (a heavy stick) and knife, you should use a fixed blade knife that is fairly thick– and accordingly heavy. One with a straight spine (top edge), full tang and a flat ground blade will make the best wood splitter.
I would give your Spyderco a good run for the money before you spend more. If you are just shaving sticks and small branches, it will work fine.
