<span style="font-family: Comic Sans MS">i bought one a couple of years ago as well. for me i think it's more of a love hate relationship. i love it because i hated cutting the hinge slots with a knife, but if don't hold it just right and very firm, it kind of does it's own thing with the cuts. if you're cutting through hard balsa, it's sometimes worse. depending on how i feel now while building, i either use that and CA hinges, or opt for a simple hole and robart point hinges. the cutting tool is pretty awesome though, and definitely recommend one if you have no desire to move away from those types of hinges. i don't know how many times i cut myself trying to work a knife through tough balsa, or made a cut crooked from a knife. GET ONE....</span>
