Planted Perfect's New Pruners

I bought ours from Amazon.com and have used them for a couple of weeks.

The spring load is great, the handles are thin covered with a non-stick material, and are easy for me to use even when my hands are tired from gardening.
The steel blades want to get rust spots in our climate but they are easily wiped off before storing to reduce that problem.
