I ordered one OST dibble bar to see how they worked . I now have three and I'm ordering another one soon . I'm using them in sandy soil planting evergreen seedlings and use to use a pick axe with a mattock head . These cut my time down to half . I have not had one break and I have to tell you I have used them for other jobs such as prying boards off a building .
