As others have said, the CS hawks can hold a very nice edge within reason. I stripped and convexed the edge on mine, its thinner all around and bites deeper into the wood.
Its not hair shaving sharp, more like utility sharp, sharp enough to do the job but not dull as to cause a dangerous mix. I dont like my hawk shaving sharp, I have rolled the edge twice in a row after getting it to shave hair, ever since I started getting it to a working edge, it has not rolled or chipped but done just fine when chopping.
