I have a folding cutter from Home Depot. It is bascally a folding knife. It is easy to use. Also, it has a belt or pocket clip.
I don't think you can store blades in it. It only cost about $8.75 and comes with some replacement blades. Very inexpensive and practical. You can go to home depot site and look for hand tools. The brand name is Husky and comes in different brilliant colors like red, and blue.
