Another vote for novelty. I've used some of the super steels on the job and not had a lot of luck with them. Whether I'm making gaskets, scraping gaskets, cutting out sprayed insulation, opening bags of c-mix or cutting miles of dirty road fabric, the knife is going to need to be sharpened at the end of the day no matter what steel it is. I much prefer spending 5 minutes touching up aus8 than 30 minutes filing the chips out of zdp189 or even vg-10. That brown FFG endura I had was terrible for chipping. YMMV
And there you go. A man that uses his knives like I do.
I wouldn't go as far as to say the "super steels" are a novelty, as all the steels we have today started out somewhere as "super steels". I remember when 440c came out big in the 70s (note: I did not say debut) and we were all astonished. Who could afford it? Who would need it?
And then the carbon steel devotees proceeded to express their disgust every time it was brought up as they associated stainless knive steels with their crappy kitchen knives or the early offerings of stainless from different makers.
I don't understand the need for the super steels myself because I am in construction and use my knives
literally all day. I don't cut up an apple or sandwich or just break down a box now and then. In addition to
Chris' comments, add cutting shingles and sheetrock, cutting molding, cutting through fiberglass banding when material is delivered, opening appliance boxes, cutting adhesive tubes, and on an on.
Regardless of the steel, and I have all the way to Kershaw's 110V, they all need a few swipes on the rod at the end of the day to get them ready for work again the next day.
I think it is important to see how knives are used on this forum. When knife pictures are posted, 99% of the knives are in like new condition, even when the user proudly proclaims the knife to be a favorite, carried for years. So IMHO, having a super steel is like a guy buying a super sports car. No, he won't ever use all 600 hp, but if he needed it, he sure could.
To me, if a knife is to be used as a tool, the knife and the steel are user specific as are all my construction tools. I don't buy the finest grade German or Swiss made wood chisels that last forever when cutting soft woods as I know I might hang a door that is made from white oak. My $65 each chisels roll the edge and chip on that stuff just like a $15 chisel. Yet in the field, I can touch up the $15 chisel in a couple of seconds. So matching the tool to the job is the key to me.
That being said, I still think that some (certainly not all) of today's "super steels" will be ho hum stuff and the norm in 20 years.
