Thank you guys!
Alan, that is indeed horn
Mathew, I am hoping so
Myles, It is a bit deceving, the edges are over 2mm thick and to compensate, I ground in a deep wide fuller. I understand that these swords often had little to no fuller so I am thinking that this would acuratly represent a sword from the period in regards to handling. It weighs 2 lb 6 oz.
