That is not a evil bayonet but one for pioneers, used as a saw. Though I never saw one that late, Mostly in WW1 and before.
When you think about it, whether it had saw teeth or not, sticking a bayonet in someone is usualy fatal.
I've only seen a couple of those longer India SLR bayonets but this is the first I've seen with a sawback. Kind of cool looking. From what I gather the correct scabbard is either a longer version of the No5 or a shorter version of their leather '07 type.
The first bayonet isn't a fake. It's simply misidentified. However it's misidentified to the tune of about $120 in the sellers favor!
That third photo is of Border Security Force (a paramilitary force) jawans on parade.These are working camels used to patrol the border with Pakistan in the Indian states of Rajasthan and Gujrat.The decorations on the camels are traditionally used in these two states.The Indian army is one of the,if not the most colourful armies when on parade
The bayonet with the saw teeth is an obvious fake,as has already been pointed out.
