I have a way to do it whenever i dont want or can not go to the shop.
I tape the spot where i want to cut them with a piece of this papertape you use for painting.
I mark the place with a edding marker and put the arrow in a electric drill.
I take a very sharp knife and let the arrow spin as fast as possible over the knife, making a strait cut.
Yes, i burned my fingers more than once doing this, but the effect is good.
The carbon never splitted on the cut.
I did it with alu to, using a sawblade.....
It works...
A high speed sawing blade is better tho...
