Zwickey two blade Eskimo-classic , proven, eye pleasing shape, easy sharpening, good flight.
Ace-same qualities as the Zwickey plus a good factory grind
Magnus II- As above
Eclipse-As above (minus the good factory grind) plus harder steel and tough and slick teflon finish.
Ribtek-simple genius in design.
Tusker Deltas-Tough, cheap and lethal.
Bear Razorheads(glue-on)they were Fred’s heads. They are about the easiest heads to get sharp ever made and usually will fly well even with less than great tuning or lousy releases.
Obviously I am not very brand loyal in an exclusive sense. There are other heads that I have taken game with that I don’t wish to use again (Whiffen Bodkin-too soft and hard to get/keep super sharp, Delma MA2-ferrules tend to split under hard impact, Snuffer 2 blades-I like tougher tips, and-this one is sacrilige-Grizzlys.- they are tough, fly great and will take a great edge but IMO they are a little TOO hard. Heads that dull files quickly are a pain in the behind.
