The Valley Oak wheel hoe is a fine one! I’ve owned one, a rubber wheel model, for around five seasons, haven’t broken the original blade, or anything else! From the company site: “This high-quality wheel hoe is designed and manufactured by an organic vegetable farmer who knows what it takes for a tool to provide years of service. You can also use this valuable tool for making furrows or loosening compacted soils. Built to last for decades of hard use. Tempered spring steel blade available in 7 sizes from 5″ to 18″ blade. New cam lever adjusts handle height quickly—no tools needed. 1-year money-back guarantee.” With metal or rubber wheel: $265 US.
