Because metal knifes scratch the bottom of my aluminum pan. And because I am impatient and can't wait for them to cool when they come out of the oven, and straight out of the oven they melted the plastic take-out knives we had.

I printed in PETG because it is supposedly food safe and shouldn't melt when you are as impatient as I am. The blade is somewhat flimsy, but sufficient for brownies.

Thanks, Enjoy! Brownies! Yum!
