My husband is a airplane model enthusiast and often uses Xacto knives as part of his modeling. Not too long ago, I bought him a new set because his were not sharp enough for what he needed to do. He gave me his old set which I was glad to accept. I do a lot of scrap booking and was needing a set.
Even though he had a new set, I just knew that if I did not somehow mark the boxes, he would get mine mixed up with his. Enters my daughter.
She decided the best way to solve the possible (and most likely probable) problem was to decorate the boxes each set came in. So, she took to marker and pen and decorated each in her lovely style.
Now I have a set of Xacto knives to use with a style all my own and I couldn't be happier.
