This pot is surely the best option for you.
It can be used on the work shop oven, every usual stove in every hostel or wherever, and every sort of camping stove, you can hang it under a tripod over a wood fire and even bake bread in it.
It is large enough to wash your socks and underwear in it, one after the other, and to melt snow in it to get drinking water.
It's currently out of stock, and you can buy it later as you also can survive without it, but I recommend to buy it if possible.
I would put it on top of my tent or tarp in one of the side pouches.
You eat with a usual stainless steel spoon from the flea market directly out of it and don't need an extra plate.

It is always a problem to carry nail scissors in a rucksack, because they could destroy other equipment.
That's why I recommend to you to have always this knife in the right pocket, attached with a cord to your belt, that you can't loose it. If the cord is 60 cm long you don't need to detach it if you use it.

If you have another knife and other nail scissors you can buy that later. I just tell you here the best and most sensible option for you. This knife is UK legal to carry, so it's worth the investment.
After a few years the spring of the scissors can break. Every shop that sells Victorinox knifes in every town can replace this spring for approximatly 1 £. You also can get there the replacement tooth pick and tweezers.
They also sell a blister needle that fits tight enough into a little hole in the plastic handle next to the point where the corkscrew is attached. It is sensible to invest the few cents.
Into the corkscrew fits a little grey handled screwdriver for eye glasses that also costs next to nothing.
