Neversink Mutineer and Colinear Hoe Kit
Effectiveness Very effective at killing small weeds and getting under drip tape. I do find that it needs filing pretty frequently to maintain a sharp edge. I carry a file on the carabiner with the colinear hoes.
Ease of Use Straightforward to use. I have found that over time, sometimes the lock mechanism gets jammed up, but with a little effort it always comes loose.
Durability Sometimes the locking mechanism jams up. I have broken one of the colinear hoes off at the weld before.
Look, Feel, & Ergonomics The weight and feel of the ash handle is great. I love the length and angle of the blade which allows for weeding with good posture.
Versatility Having the ability to swap hoe sizes quickly is great. At the end of the day, its only a hoe and can't perform any other function.
Price At about $100, its a good investment.
