why are they called pig stickers?
As far as I can gather, it's a North American colloquialism; the British version is 'Oval Bolstered Mortice Chisel'. However, the use of the phrase 'pig sticker' for an OBM chisel seems to have crossed the pond in recent decades.
A quick interweb image search brought up a lot of Peppa Pig stickers, and some fearsome looking very heavy-duty knives. The phrase 'sticking a pig' used to be used to describe the action of despatching one for the purposes of turning it into chops, bacon and pies back before the days of humane stunning (among other, arguably less savoury activities); presumably this required the use of a fairly substantial tool, hence the use of the phrase to describe something large and sharp.
