Money no object for BH choice I'm still impressed beyond belief by original German Silverflames. Can't speak for the Grizzlystik versions (think they are made to spec but in Asia??)
The German ones are the sharpest out of the box broadheads I've ever handled, and I mean "wipe" the hair off your arm sharp. The steel appears to be top quality with some really deft tempering and sharpening. These are the only heads I've handled where I was a little nervous about getting careless handling them. I have not torture tested but I have seen reports that they are very durable when going up against bone. That being said, my go-to for cost effectiveness and to practice sharpening skills are Woodsmans and Magnus Stingers.
