This pruner is not at all a rack secateurs, I bought it for this function after having tested in a living room (no Fiskars brand). Nevertheless it cuts very well for pruning shears sharp cut, but as soon as one addresses a slightly larger branch must go about it in several times by rotating the shears around the branch unlike a rack .
Also written on the packaging is a cutting diameter of 26mm and not 20 as in the description, is better, but incorrect ...
