Scimitar help.

I've been wanting to make a Scimitar for awhile now. I drew a pattern for what I thought it should be, and ended up with a 12" blade 1-1/4" high. I was planning on using .100 stock. I had a friend that does professional BBQ bring his Scimitar over to compare to my drawing. His is 14" long but he said it's almost too long and he would prefer a 12". I was surprised at the height of the blade 1-3/4" and the thickness was .130.
My question is, is there a reason for extra height? Any reason a decent Scimitar can't be 1-1/4" and thinner material? Any help or suggestions are welcome.
