Having just a little experience in this area, I'd have to disagree with all the above.
Skychief, If you're asking because you consider yourself somewhat sharpening impaired, it's far easier to re-sharpen or touch up BHDs like Magnus Stingers, Steelforce or other heads that come sharp out of the pack than it is to set the bevels and complete the intial sharpening of each BHD. (which needs to be done with any of the laminated tip, glue on BHDs). After the intial sharpening though, laminated tip BHDs are no harder to sharpen than the ones that come sharp out of the pack.
