I have been using the olivewood Joker carbon, slippy so no lock and a legal EDC. Its waylands fault caused by his little review a while back. Great knife for the money and with a little touch up, sand oil they are lovely.
My usual EDC is a UKPK but I like a change and the joker is much more "friendly" looking and MUCH cheaper to replace if lost.
If was were being very picky i would only mark it down becuase it cannot be opened with one hand.
