I would use CPMS35VN, but O1 or 15N20 or L-6 will work fine....even 1084 will do for a turkey carver.
I would start with a bar steel .100" thick. A piece of 1.125 or 1.25 wide stock will be a good choice.
.080 would be my choice for final spine thickness, tapering to .040-.050 at the tip. The edge should be a full flat grind, with a very acute secondary edge angle...about 10 degrees per side is a good angle start with.
Pre-shape the profile on the grinder, harden and temper, then grind the bevels as a full flat grind after HT.
Leave the spine straight, and when grinding the final edge, add a slight rise to the edge toward the tip....about 1/4" rise is all you need on a carver.
A Wharncliff tip is a good choice.
A 10" edge is a big knife, but this is for a special occasion, so it should be impressive.
Make the handle from a stag crown, and have a small ,narrow, guard at the finger.
A piece of mokume as a guard and butt cap, is a fancy finish, but nickel silver or brass will look good ,too.
