It all depends on my enviroment and what I am wearing but now I carry about 3-5 blades on me, of late a Gerber Applegate/Fairbairn Covert Folder, two Spyderco folders, my neck knife, plus my koppo.
If I can get away with it, I go quality fixed blade combat knife, and two folders-plus neck knife
I am not that good with flexiable weapons yet, so I don't carry any, I would end up wacking myself in the ******, if I had a CCW I would carry a firearm.
I am also working carrying on a pair of cheapo but durable throwing knifes in addition to everything else.
On the aspect of everyday weapons, yes those are a very important factor to consider, but Huang, they are no way a substitue for superior tactical weapon, if thats all you got fine, but I would not want to take my bic pen against a Busse Combat knife or a box cutter for that matter.
