Larry,
I hadn't seen this thread when I talked to Nick, and I may have posted incorrect info above. Sorry.
Thinking back to the conversation, I'm sure that the ferrules will be steel but, I think he may have said only the jumbo size will use the titanium blade and the smaller, 200 gr. heads will have steel blades. I'll find out for sure this week and correct any errors.
Anyway, titanium sharpens faily easily. I use a little extra oil because titanium can clog the stones like aluminum does. Other than that, I've never encountered any problems sharping titanium heads.
Steelforce is second only to Silverflame as far as out of the pack sharpness goes though. So I doubt that sharpening either of these heads would be much of an issue. Either the knife sharpener or the broadhead sharpener will do the job just fine.
