FlexiFlips are great for cuffs, socks, hats -- any time you need a double pointed needle, you can use this clever combination of a circular and a double pointed needle.
With FlexiFlips, you can do circular knitting with three needles instead of four. FlexiFlips are an awesome innovation that can give your hands a break.
Or try Flexiflips with dual tips. One tip is slim and pointy; the other is more blunt. Great for sock knitting when you want to get that needle point into two stitches for a decrease.
