It is a little concave before the nib.
For those that don't know. In the the Penn State 7mm kit you receive 20 predrilled mini blanks and 10 predrilled maxi blanks. Both are rosewood.
I did the best I could matching the wood.
Looking at the maxi blanks which are at least 5 inches long, the holes are drilled from both ends. In several of the blanks, the holes end up off center in the middle.
I am taking my time to figure out the best use of the wood for the rest of the kit items.
