i've been using Tusker b'heads for years,my favourites being the Aztec and later on the 190's. Getting that initial edge can be a task in itself. I tend to use the big aggressive files u find in auto repair for the initial edge. Afterwards normal files,stones and strops turn them into a very durable , affordable broadhead that takes a scary sharp edge. Two years ago , i killed a large mountain boar with a spine shot, hitting the old brute near the top point of the shoulder,shattering his spine. The boar dropped intstantly, luckily falling the right way leaving my tapered cedar undamaged. Retreiving my arrow, the 190 Tusker remained undamaged and scary sharp, despite the heavy bone collision. On the way back to camp i took another smaller boar with the very same arrow. Along with Ribtek, Tuskers are the best bang for the buck around. John Tielzel's huge water buffalo trophies probably agree with me....
