I have been collection knives for a few years now. I have about 40 Darrel Ralph folders. Some are Talonite and Stellite blades, others just ATS34, 154V, etc. My question is: Are Talonite and Stellite blades in demand or demand a higher price on the second hand market. I know that they do when you purchase them. Are those blades any better than regular steels? I do not wish to put them on the market at this time, so this is NOT a for sale listing. Just want some input from other collectors. Thank you, Robert
