Support BladeForums! Paid memberships don't see ads! Hi Folks, I am preparing for a vacation up in Boulder/RMNP this October, and I definitely want to take a good fixed blade along with me for hiking and such. Since I live in upstate NY, however, the term "concealed", as in "you cannot carry a knife concealed that is over 3.5 inches" is not as crystal clear to me as I would like (call it long-held paranoia). Any people from Colorado willing to fill me in on what qualifies as open carry of a knife? Is your fixed blade concealed if your shirt falls over part of the sheath, for instance? Thanks!
