Totally agree about the pricing being wild. I've been using a navaja for the past year and it's honestly underrated. Sure it's not as flashy as the expensive ones but the animations are smooth and some patterns look really clean. Price difference is huge too - you can get a decent navaja for what you'd pay for shipping on a karambit. Check out
