I really like the convenience of these tools. I just put all of them on a long string and keep them around my neck. The perforated one is my favorite since I didn't have one already. Buy them by the set to save money.
This is a great addition to my toolkit. Love the way I can fold them up and take them with me. I especially like the perforator to either decorate or to actually make a perforation. Genius.
These tools are small, compact and easy to use. I keep them on my desk so they are close at hand for cutting, scoring and perforating my projects. It's easier to grab these tools for quick cuts or score lines instead of bringing out the big tools.
