4" Universal Tool:

Holes for knitting needle sizes from 000000 to 35 are also clearly marked with metric sizes. Crochet hooks sizes B through P are etched above the hole where applicable to ensure it is universal for every type of craft. A cut out for measuring a 4” gauge swatch has a ruler that is marked with both centimeters and inches.
