  1. The other day I came back to my bike and found I had a flat tyre. After
    removing the tube to find the puncture I examined the tyre and realised
    I'd have to throw it away. Here's a picture of the cut, which is in the
    sidewall, not near the contact area of the tyre. The business part of
    the cut is about 1cm long and a neat 1mm deep - it exposes the white
    liner inside, except where it went that little bit further and got the
    tube as well.

    Here's a picture: <http://www.esquivalier.com/?p=28>. The straight part
    of the cut is a clean line. Obviously this was done by something very
    sharp, but what? How could the sidewall be cut like that while riding
    (on the road)?

    A sharp knife?

    I cannot see how you can get a cross cut whilst cycling, unless you're
    pulling sliding skids.

    It maybe that you have a local weirdo who deosn't like bicycles?

    A stray piece of barbed wire perhaps? Or could it be a malicious cut?

    It looks to me like you rode just alongside something with a sharp
    edge, that was too heavy to get pushed (much) out of the way. The
    cut looks slightly curved, and if the convex side is towards the
    direction of travel that would make sense.

    Rob had a look and he says it looks like it was done with a piece of
    metal, possibly a blade - anybody taken a dislike to you recently?

    Or the business end of a broken bottle? Mrs. Hall once told me she had
    a puncture, caused by ridig down a subway with a broken bottle in it.
    I was going to use it as a teaching session for her - first take off
    tyre, then locate puncture etc etc. However on picking the bike up the
    tyre nearly fell off, having been more or less cut right through,
    contact patch to bead.

    a local weirdo who deosn't like bicycles?

    I once parked a cheap bike outside a B&B, but the cantankerous old git
    who lived next door didn't like me parking it in front of his nice tidy
    garden. So in the night he put a kitchen knife through both tyres. The
    new tyres and inner tubes cost more than the bike itself (and I had a
    long walk in the morning).
