I like serrated blades in the kitchen..used on soft stuff like bread and tomatoes. I like a regular edge for the pocket or field.
Frankly, I like the old carbon blades much better than the SS stuff. Yes, carbon will discolor..but that is to be expected. As far as rust is concerned we shouldn't treat any of our knives like that. I dealt in knives for years and even took some trade-ins or discounted a new one when somebody handed me their old one (even if it was worth zip).
I still carry some of those old carbon trade-ins. Can't get a quicker, sharper edge on the SS blades (IMO).
If you definitely want a serrated edge knife...Cutco; located about 25 miles from my house has some teriffic knives with an unbelieveable lifetime guarantee. They are unbelieveably keen with their own design serrated edge.. If it ever gets dull, Cutco will resharpen it free of charge for as long as the knife lasts. If I bought a Cutco at a garage sale and it was defective...like the Zippo lighters of old..just trade it in to the company.
Beautiful cutlery..but at a high price, 4 or 5 knives in a block can run several hundreds..sold by personal contact salespersons only. I have a veterinary friend that hunts locally and harvests a couple caribou in northern Quebec annually. He has the orange handled Cutco serrated and has yet to send it back for sharpening. The knife is so keen that this veterinary of nearly 50 years experience which includes much surgery, cut his own hand quite severely, so be careful. Still, I like carbon..but with Cutco, the company takes care of the sharpening for free.
