I usually cut and fletch my own arrows. Tubing cutter on my aluminums back in the day. On the carbons I used a Drimmel Tool with cut-off wheel that gets close to square and then I use a honing stone. I've always thought that was close enough, and I personally cannot tell any difference in flight or performance when compared to shafts cut at the Archery Pro Shop on a real arrow cutter.
Thoughts about using an "arrow squaring tool"?
