These folding knives are an absolute little weapon for a Everyday Carry blade that will handle almost anything. 
There is many "flipper knives" on the market but not many as smooth as this and can be operated from your thumb or index finger with a single action.
I personally went through many brands and sizes of knives along our travels looking for the perfect flipper  at an affordable price and eventually found this, it is light weight, lovely to operate and great bang for buck. The "Slim" verison feels great in the hand and has a little more stealth than it's big brother.
Either knife is a great all-rounder it just comes down to how compact you want it.
