Polkat, #1 you do not measure a broadheads cutting diameter by measuring from one blade to another blade. It is measured, on a four blade head, from the tip of a blade across the furrel to the tip of the same blade. While I have not tried the "standard" heads with the 1" blades the "magnum" blades are exactly 1.125 inches wide.

Every single blade I have tested has shaved hair and is very sharp.I haven't found a dull one yet. Of course I am sure that one will slip out every now and then. Garry will make it right.

NAP nitron only came out last year where as the Slick trick has been out for 5 years now. So I think the Nitron would look like the slick trick. But I see no resemblance between the two at all. They are two completely different broadehads.
