I've started collecting knifes, my first knife is a kabar I paid £30 for, apart from kabar what other makes are good?.  Considering the fact that your British you should buy a Fairburn-Sykes Commando dagger ,it would compliment your KaBar as both were WW2 issue.It would not cost much more than the KaBar.A Lee Enfield bayonet would also be an affordable investment, that and the Fairburn dagger were the standard edged weapons of the Commonwealth armys.
