Yes, you can.
Graham Bros includes a nifty pocket sheath that works quite well.
I don't carry it often, as here in California it's illegal to carry "concealed" fixed-blades, and I'm not sure how an LEO or DA would characterize a Razel carried in a pocket sheath, which "conceals" the blade, but leaves the handle in plain view.
I think in the end it would be okay, at least in part due to the obvious utilitarian design of the Razel, but who needs the hassle?
