Been using a Spyderco Triangle for many years. I've sharpened HS lathe tools by hand with stones and used stones for knives early on. It doesnt take but a New York minute to lay on a razor edge with the triangle sticks.
If you have a knife made with a good alloy steel, you dont need to sharpen it very often. The best knife steel I've found is D-2. There are others. GregH
Can you name a few specific brands and/or models that use that steel, Greg? I've been looking specifically for a good spring-assist or boot knife. The knife market is so flooded with cheap trash anymore that I'm overwhelmed. The once-trusted brands are infiltrated with import junk and it's easy to get burned.
