Purchased these primarily for taking cuttings for propagation. The initial pair had a slight defect, which Japanese tools very quickly rectified. Since receiving the replacement pair a week ago, I've taken hundreds or cuttings and found them to have an incredibly smooth and precise cutting action, with no tearing of leaves at any point along the blades.
The addition of a choice of springs, is fantastic! My colleague who also bought a pair, uses a different spring to me and that customability really elevates the product.
I anticipate these to take hundreds of thousands of cuttings each year, for a lot of years to come!
