I am more into "Universality" so I wouldn't buy an arrow saw.

What i use is a 670W agle grinder with 11k rpm with a solid, metalic holder.



Anything I had to do after was adding an inch/cm stripe [8D]. Oh, and it can cut up to 6 arrows at once...
Now I can use this for lot more things (stone, metal, wood, glass) and get the confort for 42.16$

Note, this may be a little more noisy as those "pro" arrow saws.
