I'm thinking underneath the sport coat or some other jacket I wear 95% of the time. Something to pull out if and when the situation would call for it. (If you walked through my neighborhood, I think you'd understand.... not 'violent thugs with MP5s' or anything, just street punks with a penchant for mugging people.
I used to live in Hayward, which had a similar atmosphere. If you want protection, you'll carry something that supplements training. A decent, traditional fixed bladed knife will be easier to conceal, will imprint in clothing much less, and has fighting systems that are easier to learn due to availability of techniques. You'll be hard pressed to find proper martial handling of a khukuri.
