That looks good. The tiny finger grip won't be such a problem. I can tell you that you will probably round it a bit more in making the knife, as it still has a point.
There is a "rule of thumb" that says...the only point on a knife should be at the tip.
email me that sketch and I will print it out full size.
Now, about steel choice:
You have the options of several steels. The ones I keep on hand suitable for this style blade are Hitachi blue steel, CPM S35VN, and AEB-L. For a knife you want a really sharp edge on, the Hitachi blue is really good. S35VN is a great stainless with a dynamite edge... and long edge holding. AEB-L is a stainless material that has a keen edge, but lower edge holding. I call it stainless 1080.
