How tall are you? I'm 5'11". Can't kick my blade while in stride.
You wrote:"Hanging at my side is fine, but my foot constantly kicking the blade is annoying, with every step. If you are talking about the 31" Sampson, I have to say, I couldn't kick the blade while walking, with the 31" hanging from my belt carrier, if I tried. Maybe you need a different holster for the 31" Sampson.
As far as the Nomad shovel...it way to long at 39 inches. I would maybe use it in a remote field or woods, away from all public view, but that's not my hunt-place preference. I'm a city hunter 90% of the time.
The 31" Sampson is, IMHO, the best ergonomics in a shovel length digger, considering you hunt any kinds of public property.
