Didn't know how to label this one. I like the fact of a 2 blade slicing through more easily. Since the Zwickey has the bleeder blades set back a distance allowing the 2 main cutter blades to do their work first, do you think from experience that the 4 blade would penetrate just as well. I like the idea of having that extra cutting going on in case of a marginal hit. What do you think? I've never tried these.

I have shot Zwickey Delta and Eskimo 4 blades and have never had a penetration problem. Most of my shots have produced complete pass thrus and I killed alot of animals. That being said I always hunt with 50 - 65# bows and very sharp broadheads. The Zwickey heads are easy to sharpen, the bleeders are mainly done with a file and steel the main blades with file then stone and then steel. I've used them for 35+ years and haven't found anything I like better.As far as positioning I don't believe it makes any difference as your arrow spins as it goes from the bow to it's target anyway.To me it's if you prefer to have a certain site window look with the head position then go for it, but it does matter to me as I don't look at the arrow point when I shoot anyway.

What is your draw weight?

What is your draw length?

What is your arrow weight?

What game are you planning on shooting with these heads?

I shoot 50# at 27"draw length. Gold tip traditional arrow /w 50 gr.brass insert and 125 gr. broadhead. Total arrow weight of 540 gr. Mostly hunt deer. Have taken cow elk and black bear and antelope with 2 blades with very good results. Just thought I might like the results of the 4 blade on blood trail.

Have you had problems with 2 blade recoveries?  I have a 27.75" draw, arrow weight of 575, and draw my bow to 49#.  I like using a bleeder blade or a 3-blade on whitetail but prefer a 2-blade on mulies and elk.  If I had to pick one for everything I hunt it would probably be a 2-blade.  And of course, scalpel sharp.

You wont have a problem on Deer, lopes or bear with a Z 4 blade....I'd suggest the No Mercy over the Eskimo if you don't want to use the Delta...same width but better angle of attack.

I've been using the Z Delta 4 blade since the early 80s, and am still using it as my #1 head, and for the reasons you stated.  Leaves more of a hole than a slit, the bleeders aren't that wide to impede much penetration at all, and they help negate arrow pinch.

I used a two blade with bleeders for the first time this year. Very impressed with the hole they leave.

No I haven't had any recovery problems. I'm just a curious beast by nature as most on this site probably are. Terry, what you stated is basically the information I was looking for. Thanks

Have used Zwickey heads for years; both 4 blade delta and Eskimo. Had complete arrow penetration on a Shiras moose with a selfbow using a 750 gr ash arrow. Easy to sharpen with file.

Mike,just curious to your bow weight on your moose.

Me to, that's awesome on a moose.

Does anyone have a good deal on Zwickey Delta 4 blades. Need a good deal so I can convince my wife that I really haven't spent that much for Christmas.

Just make sure you get them bleeders sharp...its really a cinch....

Zwickey Sharpening thread

64 lbs @28" and I draw 27". Two things really helped with the pass through penetration; the bull let me get within 10 yards and I missed ribs on both sides. He trotted off about 40 yds, stopped and looked back at me, then tipped over.

Check out Braveheart Archery, saved a little when I ordered 4 blade No Mercy's.

I've tried a lot of broadheads over the years.  Have kinda came full circle.  Now I shoot two heads pretty much exclusively.  The Magnus 1 2-blade, and the Zwickey Delta 4-blade.

Love them both and shoot them interchangably. Have only shot the Delta 4-blade, haven't gotten into any of the other offerings from Zwickey.  Why change when you find something that works for you?  

Again, I also have used Zwikee 2 bld and 4 bld for over 35 yrs.  I have taken caribou, moose, deer, elk, mt. lion, tons of turkeys, hogs, etc.  I don't know a better head.  I also thought I needed the 4 bld for moose and caribou, so that is what I used.  However, I think the eskimo 2 bld is enough. Either way, you can't go wrong.  I shoot a 70 lb. recurve and have shot thru every animal I have taken.
