I'm still using my father's - approx. 70 years old (the hoe, that is).
There are a lot of choices . Cheap to ouch. Still got my dads . Cried when I found it in his shed when we cleared his house. Use to wake up to him hoeing early summer mornings .

Ah, found the one I was looking for ... more info here http://www.gardenersworld.com/how-to/projects/video-projects/how-to-hoe-effectively/157.html
I don't get on with a Dutch hoe but I do like my double balded push-me-pull-you hoe head in the Wolf range. We have two of the 6" wide and one of the 4" so both of us can play and they attach to a range of available handle lengths so can be used kneeling for close work or standing for clearing a larger area or veg bed.
Absolutely. The Wolf push-me-pull-you hoe is the best tool I've ever used, and worth the price.
Sarah - it's not difficult to sharpen a hoe with a file and/or a stone. Keep the stone in your back pocket so you can hone the edge after each few minutes' hoeing - it really does make a difference. Knife on a stick.
I totally agree with obelixx:
