Mr Emerson I would venture to say that any blade will rust. I have read people using everything from Silicone spray to vegetable oil to gun lubricant. What do you recommend to care for blades and to prevent rust? What methods do you recommend to remove rust? How do you recommend caring for those ultrapremium $2k+ folders (with those multiple wavy lines etched into the blade - sorry, but I dot know it's terminology)? Amongst your line of knives, what do you feel is the ideal for an EDC? Do you make Tantos? Is there any advantage for double edged knives? Thank you for your expertise.
