Yeah, The swedge grind is different. I believe it's mostly due to the angle of the grind as it doesn't travel/cut that far into the bevel grind like it does with the Tiger. Kind of like laying the blade more parallel to the grinder doing the swedge grind with the CSF where the usual seems like a set angle/percentage for a even bevel through the length of the swedge instead of a tapering look. It's a deeper cut towards the top of the blade with the CSF but it is 1.5mm shorter in length of a grind compared to the Tiger. The cut out for the sharpening choil/closed stop pin interface on the CSF (4.5mm) is deeper on the Tiger (6mm). Height of the Wave is the same (10mm). There is a more noticeable difference in manufacturing marks between the steel liner and the Ti liner with the steel liner having smoother jimping (mistake or deburred too much? don't know). Once the knife breaks-in, liners are getting refinished so that's no big deal to me being that almost all of my EKI's have their warranty voided by personal mods and scales (assuming no issues found during break-in).
