I think the Delica is a great tool for what it is, as it is. A choil would just possibly further reduce the cutting edge. The choils are something that I'm wishy washy about, and is actually one of the things that turns me away from the Native5. For it's size, it has a small cutting edge, and that was the first thing I noticed when I held one. The Delica has a smaller blade (2.875") than the Native (3"), but the Delica has more cutting edge...Delica's blade is 89% cutting edge while the Native's is roughly 82%. We're splitting hairs here (no pun intended), but it is what it is.
