Shark Applicutter on some fusible appliqué. I bought this at QuiltCon last year, pretty much on a whim because it was sort of cute and honestly I liked the colors.
This is a 14mm rotary blade on a well-designed (and as mentioned, cute) handle. The tool feels very good in my hand, the teal colored grip area is a little squishy, has just a little give and is a good size to grab onto. ie not too small for man-sized hands. I found that the shark fins worked really well to stabilize my fingers too. The fin made me feel safe that I wasn't going to push my finger down onto the blade which was honestly, my initial concern.
As I was using it, I was wondering if they sold replacement blades, and yes, good news they do.
Too thumbs up on this tool, if you do appliqué, especially with curves, you will love this thing. And if you like sharks, then it's a no-brainer.
