Thankyou all for your compliments. Canute, I have pics from the old Lanouville/France site, and they show full tangs, through tangs, and what would appear to be spike type tangs simply driven into the grip, or into a hole and secured with cutlers resin. The sheepsfoot blades were very common in Europe, and also show up in some digs here. Most had integral bolsters, but not all. Acually, the bolsters that appear integral were forge welded separate pieces of iron but require a close look to see the joint. I chose a design that I could make more easily and keep the cost down. Washer type bolsters/caps have turned up. Mine is a washer type slotted for a snug fit to the tang/blade. Due to the circle and dot decoration, this one would be more Flemish than Dutch. I present this knife as no more than being styled as a generic representation. It is not a copy of any one particular period knife of it's type. As best I understand it, my grip is too long to have been accepted by the French guilds, which would have demanded a length of 3 Pouces, or 3 3/16" in our measurements. Mine is 3 3/4".
