Again, go with a small tube cutter. 3 rivers sells them for about ten dollars and they work great! However, there is a small trick to using them. Do not over tighten them, just snug it and start twisting for 5-6 turns. Once the circular blade bites into the alluminum, snug it again and twist for 5-6 twists. Keep repeating this until it cuts. It usually takes this past step ubout 2-3 times to make an even cut with hardly any burs. Buy a 3 rivers arrow cutter which is just a small tube cutter for arrows. You will be glad you did.
