I have been using OLFA disposible blade knives instead of the exacto 11 , It is flat so it wount roll of your
bench . When the blade gets dull you just snap it off and there is another very sharp edge waiting right
behind it , These things dont dull nearly as quick as the exacto
You can find them at better hardware stores and some tool dealers. Initialy the expense is a little high
but I feel its worth it . BTW cutting on glass is definitely the best way to cut film covering
