The knife was designed to be a UK legal EDC. In the UK, carrying a knife in a public place without a good reason is prohibited. A sub-3" slipjoint (not the exact phrasing used in the law

) is exempt from this law ie. no reason is needed to carry one.
The vast majority of production knives that come into this category are rubbish. Being slightly spoiled as knife knuts in the technology stakes, there was a gap in the market for a UK legal EDC in high end materials. After a thread currently noted as having nearly 1300 posts(!), the Spyderco UK Penknife came into being.
Design features include: Calypso Jr-style blade (leaf shape, full flat grind) in S30V, large finger choil to help prevent accidental closure in use, ambidextrous deep-carry wire pocket clip (only the clip is visible outside the pocket), 'halfway stop' so the blade clicks to 90° on closing so it doesn't spring back on your fingers, 3 point torx construction
If you haven't guessed it, I'm a big fan. It's exactly what we asked for

Feedback from owners is generally very positive, the only point really being raised is its somewhat 'tactical' look. Another thread was started by Sal for a more sheeple/NKP (non knife person) friendly knife in response.
Considering what it retails at in the UK, £56 IIRC, you get a lot of knife for your money.
