Blade Biter
I finally get it! US and UK Techs are nearly identical in geometry, but the US (46-50) has a more rounded/thinner cap edge therefore more blade exposure.
Canadian Tech has a bigger gap, but also a thicker cap edge, subjectively feels the mildest to me.
Cap edge thickness makes more difference than overall cap thickness and cap edge thickness makes more difference than blade gap! We should have a new term "cap-edge thickness" and someone with a much bigger collection to measure effective blade exposures.
