Hmmm.. Are you using NEI? The recipes work fine for me.
for reference, 4 dirt = grass fibers, 2 grass fibers = 1 grass twine
1 dirt = 1 stones 2 stones = stone rod
2 rods, 1 stone, and a grass twine make a saw
Replace 1 rod with 1 stone for the axe
Feel free to cheat for the axe/saw if you still...
