Sheesh, Pat didn't you go to school?!
Ok, ok, they didn't teach it when I was in school either. Well not until I was almost out, and I didn't consider it worthwhile, since the "Kings" version of measurement, or SAE, was quite sufficient for me, and my rather handicapped mathimatical skill level.
Beautiful Arrow head!
You need to save up your Euros, and get him to forge you a knife blade, and a Hawk head!
Bowtarist, Marttiini of Finland makes unbelievably sharp knives, and they will litterally shave you right out of the box. they are very light, and make fantastic hunting knives. I have a bunch of them, and give them as gifts.
I think the layered blade you are thinking of is Mora, of Sweden. they have both solid blades, and layered blades. They are also fantastic knives, and will take quite a beating, and make great utility knives as well as hunting knives, and survival knives, and will also take on a litterally razor sharp edge. I have some of them also, as well as a few blade blanks. Sorry to add this to the same reply, but it does save time and space.
Again, Mark that is a beautiful Arrowhead!
