I took the Yardguard camping this weekend, and it did various chores involving the splitting and chopping of wood and food.
With the Yardguard along we didn't need a hatchet, and didn't realize that we hadn't brought one until the second day.
Bottom line, edge retention is ok under hard use. Having a second knife to handle small slicing chores is a must. I don't think that I will be selling my Yardguard any time soon.
