Having a bayonet is never bad.
It weighs next to nothing and can be used for psychological effect, as well as chipping wood for makeshift tinder.
Get one with a wire-cutter. They are insanely useful when you are out and about. Ignore serrated blades though. If you need a saw you need a saw. On a bayonet the cutting distance of a sawblade is next to useless. Get a chainsaw-chain and attach the ends to grip pieces. You can roll it up, douse it in cosmoline, and store 10 of them in a tin can for all eternity for a relatively low price. A good chainsaw-chain should cost around 20Eurobunnies, so you can afford 10 for the price of one terrible sawtoothed bayonet. They will last longer and will be far more useful.
Maybe attach a rope to both ends so you won't have to bend down as much.
Don't fall for the "SURVIVAL CHAINSAW" meme. It's a massive scam that is simply rebranding normal chainsaw chains with uncomfortable handles as something special.
