This is a great little tool! When I went for this, I honestly chose it because it was the cheapest on the shelf... little did I realize how much better it is than the other, larger versions out there. It is quite sharp and creates very precise holes. It's easy to store due to the small size, creates perfectly sized holes, and the cover keeps it from piercing anything while not in use. Serious bang for your buck (and size) in this product.
