Sorry, no prize for the winner (only bragging rights), but I would be extremely impressed with anyone who could name this handle material.......

And my question (probably more appropriate for the "ordering" post): I'm getting ready to ship this block off for stabilization. It measures 5" length x 1-1/2" wide x 1-1/2" thick--are those dimensions in speck for a Randall 12-9 Sportman's and Bear Bear Bowie without having to make any additional cuts?

Thanks.
