Some companies do a great job with 440A. I've had some nice old Camillus knives that used it. Some companies don't do so well. My question pertains to how well Linder handles it, not whether it is any good. If you have experience with a Linder knife using it, please advise. Otherwise, this question isn't meant for you.
I' ve had Linders, Bokers, Pumas, as well as countless Japanese made knives in 440A/Aus6. If you've been around knives since the 1980s you'd know that 440A knives never were "terrible", they only became surpassed by newer and better. I can't think of any established company that sold knives in 440A that were treated poorly. Have a nice life.
