I actually had a navaja for like 8 months before upgrading. People call it ugly but I thought it looked decent especially in better finishes like fade or doppler. Price wise it's one of the most affordable knives which makes it perfect if you're just getting into knife skins. You can check different patterns and conditions for
navaja knife to see what fits your budget. Just remember that knives hold value pretty well compared to regular skins so even if you decide to upgrade later you won't lose too much money on it. Better to have an affordable knife than no knife at all
