That's the way they look at the start, and this is what they look after limbing hundreds of trees. Notice the corner of the bit missing - chipped on a piece of frozen Ontario Ironwood. Also needs a new handle
Couple of usage tips, if you haven't used a limbing axe much:
1) The thing is absolutely lethal, so I recommend standing on the opposite side of the tree when limbing, thus negating any chance of cutting your shin in half (a very possible outcome given the edge geometry). At the very least, understand where the arc of the travel path may go, and keep all body parts (yours and associates) free from that arc or there will be parts removed.
2) It's a great slicer, but try not to use it too much for primary felling, only limbing, as the stresses from felling will eventually cause a premature failure. Use your chainsaw for felling, and then limb with the SFA, then back to the chainsaw for sections or rounds - saves gas with little time loss and lots of one-handed, barbarian chopping fun.
