And as for "protection," a stout hiking staff, combined with a little bit of training and practice would, in my humble opinion, be much better than just about any knife you might have (think Little John). I have been practicing a bit with my late mother-in-laws wooden cane, we have an upcoming trip out of the country and don't want the hassle of any knife in foreigh ports. Being old and worn out, no one will question a cane. Same with a hiking staff for a hiker...
