These pen-shaped Pocket Power Snips by Groves are so handy and have excellent sharp cutting blades - perfect for snipping your threads and yarn.
With a clever design the safety cap pops off and you push the cutting blades up with a slide button to open them. The cap means that it is safe, easy and convenient to store the snips in your project bag without damaging your work (or your fingers!).
These are excellent value, I use mine all the time!
