When I was "new" to knives I hated coated blades because I didn't want to see any scratches on my knives, but I don't mind a black coated blade anymore. I have a few and use them often. It's not my first choice as I would take a satin finish blade over a coated one in a heartbeat, but none of my knives are safe queens anyway and I use them all. If you carry a knife it's eventually going to get scratched and scuffed anyway so who cares? Like dennis 75 said, it gives the knife character. That said, some coatings are more durable than others. BT2 seems to be durable enough. I have an old BM CQC-7 that has some wear around the edges as well as a few scuffs marks the blade, but overall the coating on the blade is 99% intact. I have a few blades that are Black-T coated and they appear equally as durable to me. Ti-Ni coated blades seem to scratch easier as I have a Ti-Ni coated Gerber Covert Applegate as well as a Kershaw Avalanche that have been used casually on and off and have a few light scratches on the finish. For me, the least durable is that Teflon stuff used on less expensive knives like the Gerber AR 3 and the like. That stuff seems to flake off easily. It all really depends on what it is you're cutting and how often you use the knife. If you cut abrasive material like heavy cardboard, then the coating will get marred easily as opposed to cutting food items and light material.
