My favorite garden tools (besides my rototiller) are my Wolf garden tools. I have bought a dozen of the accessories and two storage racks that I've got attached in the garage. One of the stranger tools they offer is a row and furrow hand tool. I bought it out of curiosity and now it is one of my favorite tools in my collection. They are well made tools, I've never broke one and I use them regularly. They've got a wide selection of tool types. If you have one of the old "Scott's" brand hand tools, the Wolf tools are compatible with them.
