Title: 20 degree blade angle
Post by: Jim Wright on November 05, 2013, 10:18:00 AM
Since you have to sharpen almost all 2 blade, cut on contact broadheads, I was wondering if anyone has taken theirs to a 20 degree blade angle and what were your impressions?

why not? A double beveled edge at 25 degrees per side equals 50 degree. a single bevel at 25 is, well, 25.  So 20 + 20 = 40,  nothing wrong with that..

My only problem with that is occasionly hitting the ferrule when using a Lansky sharpener. I do however find a shallow blade angle sharper.

20 will be sharp, but I think 25 is a more durable edge.

However, try it and see what you think, it may be just what you are looking for.

One other way to look at it is this. Shape the general bevel to 20 degrees and the last few strokes go 25 degrees. The over all geometry will flow better and the exact edge will have some durability.

Steel and heat treating plays a part, true but this is just something that might otherwise give your edge some desirable characteristics. I do it myself.

I generally try to touch up at the factory angle, as less metal has to be removed.  There's nothing wrong with reducing that angle if you have the patience and the sharpening media to remove the metal.  The "Sharpie" trick helps let you know if you're sharpening all the way to the edge or just hitting the bevel.  Bear in mind that some fixed-agle, clamp assisted devices are stating the angle at the jaw edges. If you have a wider head that protrudes significantly past the jaws, the angle is reduced.  I like to sharpen as low as I can go without hitting the ferrule as RNB mentioned.  Some like the secondary or "micro-bevel" the Lin mentioned and feel that "shoulder" gives the edge some backbone.

Thanks for the input, I am planning to first use a hand held Smith's Broadhead Sharpener. The Carbide Strippers finish to 20 degrees and I will then use a Lansky medium/fine dual ceramic stick sharpener that has holes in the wooden box for a 20 and a 25 degree setting. We'll see how it goes but thanks again for the input.

Dont get the angle too steep, will roll at the 1st sign of a rib.

As Lin stated above -- Shape the general bevel to 20 degrees and the last few strokes go 25 degrees.
This is how I sharpen my knives and 2 blade broad heads.
