I have a couple of older Odyssee knives on layaway and have a question about one of them.One is a 2001 and the other is I believe a 2002. My question is; the 01 has a straight blade with an open back, the 02 has the same blade but with a solid back. Does anyone know if this was the norm for this year? I was going to pick them up today but got sent to Atlanta again. I will post pictures as soon as I get back and have them.
