Although they are not really parangs , the Kabar Kukri , camp knife , and cutlass machete are examples of easily purchased bush choppers. The only thing that throws me off a bit with the Kabars are the stick tang . I'd prefer a full tang for strength and " feel" . The grinds also. Convex is better, IMO ,but they could be ground so if desired.
Lofty's has a thin ground area a couple of inches back from the tip , as well as nearer the handle for finer work , the thickest being near the sweet spot. Something which I feel the condor's and kabars lack. The Kabar Camp is still a possibility. Cheap enough , although it needs the top guard ground off , and edge convexed;something I could do.
Once ground so , a diamond rod to touch up the serpentine edge would work in the bush , although any chipping if any needs to be filed out. Search continues.
