Folders -
Ferrum Forge Fortis or Archbishop, or whatever run of theirs you like the best. My go-to for EDC folders!!
A Spyderco PM2, Manix 2, or military, any of those in Cru-wear.
Calavera Cutlery El Patron. Competes with my FFKW blades for pocket time. Gets used a lot
Real Steel Sea Eagle. Very surprising!!
Bradford Guardian 3 folder
Protech Auto
My Mac Wasil customs are all great folders!
They are not for me and I sold mine, but a CRK to see if they are for you. Well made knives. Definitely worth trying for yourself!!
I would say some customs I have had, but most customs are too much to say "Must-Have".
Fixed blades -
Carothers Field knife. I have a light chopper too that is awesome!
Robert Martin at tearsofthesword CPM 3V slimline machete. My favorite fixed blade by far! Takes a beating!
Busse Infi blade. Their Swamp Rat knives are great for the price too!
Schrade 1095 steel fixed blade. I got a 7" blade fixed blade of theirs for under 30 buck, which is a steal for what you get. IMHO
Ontario fixed blade
and a folder or fixed blade in Stellite 6K. Great blade if you are a water person!
