The routine while sewing is to cut the thread with a pair of scissors (or teeth!), but since scissors are known to play truant when you need them the most, here is an alternate solution. The Cut Needle. The eye of this special needle has a sharp blade towards the lower-inner eye. The thread tends to stay around the upper eye area whilst sewing, so when you need to cut off the thread, simply snap it over the sharp blade. Teeth and scissors both are not needed! Awesome!
