How much file work and with what file size does it take for you to reshape the bevel of your broadheads out of package? I just got some zwickeys and I tend to use a 20 degree bevel and I am having to do quite a bit of filing. Afraid I'm missing something and just messing up some very deadly looking heads

These are only the second style heads I have purchased. The magnus sharpened up real nice, but I love the way these 4 blade no mercies look.

What angle do you typically sharpen too
And how much work to get there?

I think the bevel on zwickeys is usually 25 degrees? I'm not sure really. that may explain why you have to do so much work.

Make the edge solid black with a sharpie and you'll know

I personally wouldn't change the factory angle.They establish it for a reason and it usually is the best combination of sharpness and edge strength.The particular harness in a broadhead may not support a sharper angle.Those guys have been building broadheads for decades.I bet they know what they are doing.

I was doing that Kentucky. I am just now getting down to the black on the edge. I was taking a lot off the middle part of the blade before I started to contact the edge. Had me worried.

Is there any benefit in going this steep? Or draw backs?

It is the edge I use on my knives and figured it would be fine for broadheads

I use the biggest bastard I can get my hands on it cuts way faster.  Zwickeys should be no problem with the factory bevel. Some of the older Grizzlies; there you were in for a tussle to change that bevel!

I Work on the transition from the triple thick area first without touching anything else. Sometimes it can be way off. Then the work on the entire length shouldn't take long. I like a chainsaw file.

I don't change the bevel on Zwickeys.  However, do need to take off the extra metal in the triple layer front part of the head so the file will lie flat on the existing blade bevel.  

Also, many Zwickey Deltas, and I suspect the No Mercy's as well, have a concaveness in the blade.  Put the blade edge on a file and look at it from the side.  You will usually see light in a little arch between the blade and the file at the center of the blade. To get the blade straight along its entire length, I take some metal off the cutting edge of the triple thickness front. When that plane is straight, I follow the initial bevel of the blade its entire length with a file.

If you just start filing the entire length until everything is trued up, you will take off a lot more metal and usually reduce the width of the blade at the back.  Good luck.
