I've noticed that on my fixed blade old timers (15, 152, 154) that the portion of the blade closest to the handle is not sharpened - and that the sharpened portion doesn't start until closer to the tip of the blade than on most other knives that I've ever owned. Does anyone know if there is a specific reason for this? is it supposed to reduce user injuries? it doesn't work well if you are doing any heavy whittling / stick sharpening where you are really trying to bear down to remove material - for this I like to use the portion of the blade closest to the handle.
