If a person is getting into big traditional blades, then it's a good idea to read over Jean-Marc's safety advice starting here:

and continuing with his other articles to be found over at Outdoors-Magazine.
Deflections are a big issue with blades having lots of curvature, and so a person has to be very aware of safety, until skills are gained. My kuks all came with poor edges despite being better ones. It's essential to put in some work to remove any tiny secondary bevels which will further promote glances.
Traditional blades whether goloks, parangs, kuks, billhooks etc. etc... work better than a person will ever guess for the first few months of use. Eventually by accident the user will discover some version of the draw cut and find that it is not a myth. In the meantime though, it's hard to think of the blade sailing through a sapling without slowing when each chop cuts in exactly as deep as expected. One day, though, the seemingly impossible will happen. Then anything in the path of the blade is in danger.
I guess anything which is highly effective for cutting is dangerous. Just go slowly and carefully until things come together.
