I EDC a spyderco wannabe made by Byrd Byrd UK Legal Knives: Byrd Tern --- Heinnie Haynes - Knives, Pocket Tools and Accessories
and I keep a 3 blade whittling knife in my bag for when I'm bored.
P.s for those of you in the UK the rule on knives is you're allowed to carry one sans excuse if its's a non locking folding knife with a blade sub 3" (confirmed by my local police station) the only exception to that rule is if you take it somewhere where there are rules against carrying ANY knives i.e schools, planes, some government buildings. But you won't be charged with carrying an offensive weapon you'll get charged with some sort of breach of peace charge or threatening behaviour.
Oh there is a final caveat, If you stab or threaten anyone with it your previously legal knife becomes an offensive weapon (anything can be an offensive weapon in the UK if you use it like that from your J 2o bottle in the bar to a can of deodorant).
