Well I just cant not tell you about my favorite tool.
I love my Flat brass 45 marver. It has a flat smooth top and 45 beveled sides the edges are sharp and I use them also for cutting into the glass the back side is just perfect for the larger tube beads, bicones Oh and the angle is PERFECT for making even ends!! Every time I make a bead this tool is used in one way or another.
Here is a pic of the tool.
