I would think that you are referring to pen blanks, for that, it all depend on what type of wood (size/shape) you will be using to process the pen blanks from and for boards and small chunks, an inexpensible table saw will get you going.
If the blanks you are talking about are bowl blanks and the like, the chainsaw and a set up (vice type) to keep the logs steady/firm, is all you need...!
PS: for pen blanks as starters, it will be a lot cheaper to buy packs that have a good number of blanks and timber varieties, they are normally quite cost effective. There is always the request here for a little "hand" from other members for blanks they may have and are willing to give away. As my Mum always said, "you don't ask, you don't get...!)
It all depends on the tools that you do have. Cutting with a band saw can be tricky. The blades have a set and to get a straight cut sometimes you have to hold the work piece at an angle. If you are going to use a table saw get a gripper to hold the small pen blanks. My table saw is a Delta Unisaw and it will cut the hardest oak like butter. I am very cautious about getting my fingers close to the blade. I have a friend who lost three fingers using a contractors saw. Didn't even know he had done it until one of the fingers hit him on the forehead. If you are unfamiliar with a tool best not to start out trying to cut something small like a pen blank.
