Trimming ends off snow peas
I do trim them, but not as rigorously as you do. I really just take off the tips.

There is an exception to this though. The ones you show in the picture have been harvested quite young, but this is not always the case. You can have situations where the end that holds the little peas has a tough fibrery texture. In those cases I still take off just a little on both ends, but also try to pull the fibers from the side.
