I was talking to Judith, a fellow painter about palette knives and trying to describe the type of knife that I prefer not to use. It has to do with the angle of the handle and the angle of the blade closest to the handle.
In the first picture, you can see that the angle from the blade to the handle is very different between these two sets of knives. The set at the forefront has a shallow, short angle. I have a hard time not hitting my painting with my hand when I use these. I prefer the angle and length of the last two knives sitting on the napkin. Lots of room to work.
In this second picture, I want to point out the part of the blade closest to the handle. The first two knives have sharp edges. I really dislike that. The edges get caught on my painting and create harsh lines. I prefer the third and fourth knife. See how the back edges are rounded?
This is just a close up of those back edges. Sharp angles versus rounded.
