I got a Work Sharp MK.2 the other day and at first blush thought it was just another gimmick. It didn't take long to realize it's not! I mowed through my hunting knives with ease and it now has a permanent place on my kitchen counter. It is easy to use and seems quite sturdy. I haven't tried it on axes yet, but that's on the list. The only downside is it can't go to camp because we don't have electricity there. Maybe a battery version is in the works?
