These General Purpose Bypass Secateurs are ideal for delicate and precise pruning. Bypass blades work on a scissor-like cutting action with one blade �bypassing� the other. They are best used on younger growth as they provide a very clean cut, essential for maintaining a healthy plant or shrub. They can also be used on older cuttings but a little more effort may be required by the user. These light weight pruners have a 19mm cutting diameter and have coated blades which allow non-stick pruning and easy cleaning. They are suitable for both left and right handed use.
