mikromodell:
For cutting thin brass tubes I always use a knife as this video shows: https://youtu.be/lxKDMCLUsEo

Hi, I agree I use a knife and roll it but always put some wire in the tube in case the cut off piece jumps off somewhere obscure.

I use a tubing cutter.  It's made just for this job.

Same here but they won't do down to the size I think the OP is posting about unless you can post a link on a tool otherwise that will do down to 1-3mm?  (I think OP means small diameter tubes).  I also use same knife blade method in the video (doesn't even need to be that sharp, no need to waste a new blade), need to remember though it has to be rolled on a flat, incompressible surface otherwise the tube bends, and it does usually still leave an external and internal ridge.  Internal ridge I sometimes treat with a "bead reamer" if rubbing the end square with wet and dry sheet doesn't fix.

.....never thought of that!  I usually get about one part for every 4 or 5 attempts that ping off or I drop on the carpet after parting!  I changed to laminate but it doesn't help either -these little bits just roll off in to a corner somewhere!

use one for cutting brake lines, they go down really small (actually looking it up 3mm is the smallest.)
