No can do. It's what I really like that becomes unpopular or never sees its day in the sun.

What..doesn't everybody
I LOVE the screeching noise a hollow ground blade makes as you pry it out of a piece of wood after every chop. When I get a rhythm going, it reminds me of my grandmother's rocking chair. So what if it takes ten times as long to get through a limb, the sentimental value more than makes up for the physical exhaustion I might have otherwise felt from doing all that extra work. You have to learn to rationalize, and use your imagination, instead of trying to base opinions on facts, or actual work.
Screeeeech.....screeeeeech....screeeech...it's all very soothing when you get your mind right.

OK, i don´t know, how much metal Thom wanted to grind away, but again, i sharpened my S30V edge, to get a straighter angle, not the second beveled one. It was very easy to start with the Apex fine stone and go on with the Spyderco rods. Please notice: This may be very different, if you want to take away more metal, maybe a bevel 1 mm wide and more, no matter what kind of steel, but for an average edge bevel of .5 to 1 mm, no problem.
Again i found the burr fine and homogeneous. Some steels i used, were hard to get the burr on it, but this one, like other fine grained steels, took the burr quickly and fine.

Blop,
I've found that all steels sharpen quickly on the EdgePro Apex (unless I'm trying to take away too much steel), but noticed a difference with the Sharpmaker. That is, on the Sharpmaker, S30V would touch up or microbevel instantly, but it takes longer than expected to completely resharpen (not by much, though). Well, that's been my experience.

Blop :
Yes, this is the reason why you want edge thickness to be the minimum necessary for durability requirements, anything in excess just leads to inefficient sharpening (as well also produces an inferer edge in regards to durability/cutting abiltity). This by the way was what I said about Puukkos that Brownshoe is refering to in his own special way of paraphrasing.
When you leave the edge bevel 1cm+ wide, it leaves a *lot* of metal to be removed each time. Just think about sharpening an edge that wide on a S30V blade, you are now doing the same amount of work as polishing the blade flats on a knife with a primary grind, ask a maker how much they charge for a hand rubber mirror finish.
Teh reason such a profile is ineffient from a durability standpoint is that edge damage is rarely seen to a depth above 1 mm and thus only this depth of the edge bevel needs to be obtuse enough to prevent damage, above this a heavy relief can be added to both increase cutting ability and ease of sharpening - this of course is achieved by primary grinds and/or dual ground edges.
Owen :
Considering that the leading cause of health problems is being overweight, such blades should be sold on the basis of promoting "a healthy heart" as any such activity is now made several times more inefficient and thus requires much more healthy exercise. You could then leave them unsharpened for those who wanted the "advanced" program.
Thombrogan, I beg you to reconsider, just think about the wealth of good you could do for the knife industy with a few of such sweeping changes. Maybe you should try the reverse and post about how much you hate :
1) hollow relief grinds on 64+ HRC blades
2) convex chopping blades with l6 or better tool steels
3) handle and a half grips on blades to increase verstility
4) NIB edges with crisp grindlines and without hollows
This may make all of the above quickly come into production for great benefits all around.

Can't be me. Besides, the Calypso, Jr. I pined for has come back, so fate isn't always against me.
The best ways to change these trends are through finding attractive ways to advertise facts. For instance, Strider makes flat-ground S30V folders look and act amazing. Eric Fehrman makes flat-ground 3V fixed blades that are reassuring in a primal manner. Spyderco and Extrema Ratio make locks that are bomb-proof. Idaho Knife Works makes survival-style and utility style knives out of L6.
Obviously, there are several more examples of this than can be named or bought by one person.
If there's a way to entwine fantasy with reality, then there's hope for quality production of useful knives to rule the roost. If there isn't, we can all save up for belt-sanders and EdgePros to correct most of the out-of-box blemishes. I say there is because every day, thousands of knifeknuts refer green CrO powder as "rouge".
