A glass crochet hook
Glass is known to have some properties when it comes to knitting. It has a very low grip and a uniform surface with no dents or irregularities, which means supersmooth and gliding needles. To avoid breaking, these needles are not regular glass but rather borosilicate Pyrex®, which is substantially stronger, more durable, more fracture resistant than regular glass. Still the glass is still quite fragile, on the heavy side and cold to the hand. Yet these needles and crochet hook are fantasic to look at and nice objects to show off in your craft area.
