I have to say I really wish Busse kin would release two versions of their knives. One with the finger choil and one with just a sharpening divot. The Ratmandu is a great knife but because of the large choil I may not end up using it, it would be much better, to me at least, with the return of the edge length.
One reason this becomes a slight bit more important is state knife laws regulating the overall length of the blade. As an example, this is a visual estimate that hopefully gets my point across, the S6 would fit the 5.5" blade limit if measuring linear edge length. But with measuring from the handle it definitely wont. If blade length is already limited I don't want to give up extra edge due to the choil. The Ratmandu is a longer blade but has less usable edge then a shorter knife like the Koster Bushmaster.
