seems like I use a lot of #11 blades on BMF...

I was going to ask what brand you were using- I tried the Revell blades, and wasn't too thrilled with how long they lasted. With the Exacto brand blades, I can foil about ten cars before it's time to switch to a fresh one. I usually keep one new, fresh blade specifically for foil work, and once it gets dull, that blade becomes my 'general purpose' blade when the current general purpose blade in the handle gets dull.

same with mine by the time i use the old foil blade as my general blade its so dull it wont cut butter non the less plastic lol
