Surplus knives left by the soldiers sent to academy should have a use - my proposition is to exchange them for new item - scrap metal that can be then exchanged for gun parts with some beneficial rate like 3 scraps = one gun part. exchange rate should increase with base rarity of the gun - i propose 2x for every base rarity.
Scrap metal might be excelent monetisiation method aside from logistics cards/lootboxes.
god please do not ever suggest they should keep the lootboxes and monetize them, as that will get the game banned in multiple countries because of gambling.
Also, that would be borderline P2W as average players dont have enough spare guns to upgrade every single one they own, while paying players would be able to guarantee every gun they own does +20% damage, and either has +20% more accuracy on bolt actions/semi’s, or +20% fire rate on SMGs. That would just kill the game.
perhaps you’re right but i doubt that they will listen but now we have some absolutely uselss items and so i wanted to give them a purpose.
start a knife collection 
I really wish it was funny. I really wish.
Anyway what do u think about idea of converting them to spare parts? (Excluding the part about monetisation)
I think that scrap should be usable to buy weapons, that would be neat
Or “selling” weapons back to the depot for orders, for example 5 spare kar98ks = 1 order
