I think the Steel Force heads are billed as razor sharp out of the package, and I think they offer a resharpening service.
On a side note, I used to obsess about having my broadheads razor sharp, as in polished edge razor sharp, but after noticing how dull they ended up after passing through a deer I began to think that razors are good for shaving but not much good after plowing through a layer of hair and bone first.
I've been using just a regular file to sharpen my broadheads for about 10 years and feel the micro-serrated edge you get with a file is much better suited for the kind of impact cutting a broadhead does. The broadhead is still sharp even after cutting through hair and bone.
File sharpening is quick and easy.
