Even for their hatchets, the blade profile is more designed for splitting than general chopping.
At least here the hatchets exist in two variants, splitting and GP, one mostly really wants the GP one.
I own about 4 and have never had a problem but have heard that some do, scouts seem to have a way of breaking them, my daughter tells me that it happens as follows: hit it into a pine stump, get it stuck and then kick the handle sideways trying to release it, apparently that usually works (breaking the handle).
Mine have always been very sharp but then again there might be some differences.
