There's an artery on the inside of your thigh called the 'Femoral artery'.
If it's cut, a person 'bleeds out' in about a minute flat, at which point the blood pressure fall is pretty much terminal.
It's ok bill the edge is as smooth as a baby's bum the frayed bits are the heat proof sheet that I fashioned round the back & the edge so hopefully I won't bleed to death I don't know about chopping the bollox off with an axe last time I done a procedure like that it was with a a pair of garden shears it's surprising how neat a job it is
