I am not that fussy when it comes to thread cutters, though, because I'm of the general opinion that as long as it cuts through Fireline it will be fine in 99% of my beading situations. And, unlike when I started beading and it was hard to find a pair of snips that would easily cut through Fireline, we now have a wealth of options, including at least two wonderful products by Xuron, fabulous scissors by Chikamasa, tiny but tough travel scissors by Burfitt, and a few good options from Fiskars, not to mention the hot line cutters (also known as thread burners) from Berkley (maker of Fireline) and similar tools from The Beadsmith and EuroTool.
I came across my latest find, the Boomerang Snip, at the Bead&Button Show when I stopped at Karen Bruns' booth to see her latest creations. This compact tool has blades that can lock shut, a handy LED light that you can shine into the deep recesses of your beadwork, a retractable cord so you can hang it in your bead bag and NEVER LOSE IT (this is a big one for me!) and best of all, it cuts through Fireline with ease. So I am happily adding it to my thread-cutting arsenal. Its the obvious thing to do!
