My inventory is full of random skins I never use. Better to keep them or just sell everything and buy one nice knife?

Knives are solid investments compared to random weapon drops. I consolidated my inventory last year and got way more enjoyment from having a knife I see every round versus skins I barely noticed. Check https://dmarket.com/cs2-wiki/ for current knife prices because some models hold value way better than others. Doppler and Fade finishes usually stay stable while safari mesh and forest patterns are harder to resell. Calculate your total inventory value first though, sometimes those random skins add up to more than you think. Also consider if you play specific weapons a lot, like if you AWP every game then maybe keep a nice AWP skin and sell the rest
