The reason I ask, is that I always used to use just a 12" blade and thought a few months ago that if I went to use a 14" blade on all my windows then I'd get through my work quicker.
However, in reality, Ive found on quite a lot of the glass I do the 14" struggles for various reasons:
1: pane too small to allow adequate turning with a longer blade, thus creates more detailing and strokes
2: with the 14" I find its more prone to smearing
3: just too big for the width of some panes.
So now I swap between the 2 blades throughout the day, having both on hand most of the time.
Has anyone else found this?
I find the 14" is best for shops/patio doors and panes approximately twice as wide as the blade is long, so at least 2 1/2 foot in width or more.
