If you want a knife for under $100, your only real options are falchion, gut, navaja, and shadow daggers. You can get really good skins for the shadow daggers for cheap because people don't like them (they shake your crosshair when you pull them out). Otherwise, you'd have to settle with some of the uglier skins if you wanted a different knife. Personally, if you wanted a knife, I would say get: Shadow daggers - Freehand Shadow daggers - Slaughter (would be under $110) Shadow daggers - Autotronic Shadow daggers - Vanilla (would be under $110) Gut knife - Freehand Gut knife - Damascus steel/Vanilla Gut knife - Slaughter (would be under $110) Gut knife - Black Laminate Navaja - Tiger Tooth (would be under $110) Navaja - Marble Fade (would be like $120) Falchion - Bright Water Some of my personal favorite AKs and M4s would be: AK - Leet Museo ($20 ish for a good field tested) AK - Asiimov ($50 for min wear $30-40 for field tested) AK - Neon Rider ($35 for field tested $50 for min wear) AK - Aquamarine Revenge ($30 for field tested $45 for min wear) AK - Wasteland Rebel ($20 for field tested $35 for min wear) AK - Ice Coaled ($15 for field tested $30 for min wear) AK - Point Disarray ($10 for field tested $17 for min wear) AK - Frontside Misty ($15 for field tested $25 for min wear) AK - Slate (Pretty much $3-5) AK - Rat Rod (Around $3-5) M4 - Neo-Noir ($6-7 for field tested $15 for min wear) M4 - Buzz Kill ($10 for field tested $16 for min wear) M4 - Cyber Security ( $12 for field tested $25 for min wear) M4 - Dragon King ($7 for field tested $15 for min wear) M4 - Spider Lily ($2 for field tested $4 for min wear) M4 - Evil Daimyo ($2 for field tested $4 for min wear $6 for factory new) Narrowed down I would say: Leet Museo, Frontside Misty, Slate (get some good stickers) Neo-Noir, Cyber Security, Spider Lily If you want me to get you some more skins for different guns like USP, Glock, A1s let me know :) Hope this helped!
