I have recently learnt that there are few things in life as satisfying and likely to lift the spirits after a trying morning than slicing through flesh with a whetted blade. Apart, perhaps, from wielding a reassuringly hefty meat cleaver, or to use its suspiciously pedestrian-sounding alternative name 'chopper', and cutting cleanly though bone, feeling it part with a gratifyingly loud crack. I'm not sure this was a life lesson I was meant to take away from my afternoon being taught butchery at The Parson's Nose in Fulham, and I did learn a great deal about the anatomy of the pig, but, my word, the cutting felt good.
