Petzl made quite a few changes to their ice tool line up this winter. You may have seen the post from earlier this fall that was the Petzl video advertising all the new tool changes. It had some pretty cool footage on it as well. Changes were most noticeable in the Quark and also the new addition of the Ergo. The Nomic had a few changes but nothing drastic. I recently came across this comparison of the old Petzl Nomic versus the new Petzl Nomic which included a few modifications as well. Check it out here at Cold Thistle.
