Such advise is uniform across manufacturers.

Hmmm. Good to know.... thanks.

In my experience...

- Tube cutters work best on metal, the cut is square and leaves an inwards crimp. Carbon fibre cannot crimp and will splinter on the inside.

- Hand saws must have at least 2 teeth in contact with the wall thickness. If sawing with 2 teeth in contact then light pressure is best. If 3 or more teeth are in contact then heavier pressure can be used.

- Drop saws = high-speed machine cutting. The cut will be square and the tooth count is overwhelmed by the RPM. Anything will do from an abrasive wheel to a coarse saw...just take it slow on the drop!
