Great sewing tools!
I'm very happy with the seam ripper and stiletto - they look great, are easy to keep track of, and are super sharp. I ripped black thread on black fabric seams from my serger and coverstitch with easy; the stiletto is great for feeding fiddly fabrics evenly through my presser foot, and or marking spots for rivets and snaps. I bought an additional set for a friend and she loves them too. I've been sewing for 20+ years and have gone through a number of seam rippers - these are top notch tools.
Would recommend to a friend.
