These spoons go back at least to the 1600's as far as my research go's(which I'm just starting)They were made primarily from maple but some fruitwoods(apple'cherry)were used.You are correct that they have the hook so they don't slide into the bowl.The dark spoon is about 3"across the bowl.The originals that i've seen start with this size and went up from there.The block i used was 3x5 and were the cut-offs from a rifle blank.As for a finish almost all finishes are foodsafe once dried.You will get some great arguments about this but I researched it heavily for a line of commercial children's furniture I built for a while.I used Jim Chambers finish but if you are really worried use Butcher block oil made for wood kitchen counters.If you any other questions fire away I'll try to answer them!!

You are so right.I'm getting ready to engrave and carve my sons first rifle and these are a great diversion while I practice up on my engraving!!
