NO CHILD UNDER THE AGE OF 18 SHOULD BE ALLOWED TO USE THE ROTORY CUTTER! in the sewing school the kids use scissors---just like our parents/grandparents did for hundreds of years...rotory cutters are RAZOR BLADES...they are not something any child should be using...i've seen (kids) who were 19 years old---singing/dancing around, happy happy- cutting blocks...and suddenly---57 stitches later....
there is no reason why kids should not be taught to use scissors like they have for generations...after they are (experienced- have learned much- they can advance to *advanced tools*) they should not be starting with advanced tools---it's all fun & games til someone gets hurt....and a rotory cutter can be VERY DANGEROUS...it's not fun any more if you loose a finger doing it...TEACH THEM SAFETY FIRST!
