By rotating in both directions up to 90 ° cutting head can work just fine as a right or left handed and not as easily accessible to free edges and corners of the grass. I use from time to time with WD 40 the cutting surfaces to keep them rust-free and maintain. I think these scissors will long be my reliable garden tools.
For a very good and mature product with a good price-performance ratio's from me 5 stars and a buy recommendation.
