Would you use your Phrobis as a survival knife?

I wanted to post this is the general bayonet board but for some reason I can't acces it. Maybe because I have a current active post going. Anyway just curious to know if you guys would consider using this as your survival knife and bayonet? My main weapon of choice (long gun) would be my AR so to cut down on weight the M9 could carry out many tasks as a survival knife as well as an additional way to protect yourself utilizing your AR. I know there are better survival knives out there. Another question. If you had to protect yourself in a post apocalyptic world and you were out of ammunition would you choose to mount your m9 on your AR to fight or use it as a stand alone knife? Personally I would not abandon my AR because you would possibly obtain more ammo but I think I could fight much more effective and agile using the bayonet as stand alone knife.
