This is very useful. I have multiple of them as I usually can't find the one I'm looking for. They give great indication what size your knitting needles are - particularly if you have older models where it's not written on the needles.

I always keep a needle sizer in with my supplies when crocheting or knitting as some of my needles don’t show a size on them...with a handy sizer you will always be assured you are using the correct needle or hook size for you project.

This is one of my favorite and most-used knitting tool. I have acquired so many needles of unknown sizes and this helps keep me organized. It is also really thin and fits easily in my project back.

The gauge is handy, but it's the fact that I can easily grab this and measure what I'm making seals the deal for me.
This is my companion for when I make headbands (for measuring the width).

It seems strange, but this needle sizer is something you will need if you are an avid knitter!
My needles have lost their printed number, so this needle sizer is so helpful for me!
