At what angle do you sharpen Zwickeys? I use a Lansky for my knives, can you use it fot thses heads as well. I will be shooting the Delta 2 blade, or the No Mercy head

Thank you in advance

I uses a lansky on the zwickey eskimo broadheads.  Don't have any No Mercy heads, but if they are double bevel heads I would sharpen them the same.  I use the 25 degree slot on the lansky.  It seems to be the best between durablity and sharpness.  I can get them sharp with the 30 degree slot, but think the 25 is sharper, even though I can not prove it.

there is also video of sharpening them with a lansky sharpener on the 'how to' here on tradgang.
