Overpriced for sure. I can think of a dozen blades I would rather have. Aluminum handle is hitec materials? lol. Please. The entire frame should have been made for HT'd Beta Titanium with CF inlays for how much they charge. But then again I saw some of their fixed blade prices and laughed. A mid saber grind blade profile that is additionally convexed to the edge makes for a very obtuse blade geometry. The polishing gives it a long lasting finish against abrasion and the 67 Rc will go a long ways. But once this thing goes dull, you will have some fun putting a profile on it. Also the edge is so thick that even with the polish it did not cut the paper so easily. My Spyderco K2 does a better job than this thing at slicing through paper, but it has a proper blade profile for cutting.

I have to agree with much of that.

Their newer stuff is using Titanium handles. They were just slow to catch onto the whole titanium thing.

I have to agree with much of that.

If we’re judging Rocksteads by their handle or even materials then they are overpriced. What they are selling for such a high price is all the hand work that goes into the beautiful blade. Everything about the blade is what makes these knives what they are.

I guess I look at it as though people pay 1500$ for an impressively built handle with an impressive action from Shirogorov or a custom maker all the time.

When paying 1500$ for a Rockstead what you are paying for is the other end of the knife, the blade.

Or you can pay just over $2000 for both. Sinkevitch design with rockstead blade.
 
They are undoubtedly exquisitely finished knives. The one in the video doesn't do much for me. It looks like an overfinished stubby pry bar. But I'd take a Higo with its more usable blade.
 
I get that the money is in the blade, or so they say. But if you are using a laminated steel for toughness and strength, then why design the profile to such obtuse standards? A tough laminated steel blade could have had a much thinner profile for cutting ability, all that polish is worthless when you make the edge so thick. At this thickness, this blade should have been completely flat ground.
 
Always wanted to get to handle one in person, but, that price has always held me back, that plus the really smooth handles makes it look slippery even with the small bits of sting ray here and there.

The convex grind helps give it superior edge retention. The thickness is what makes the blade so impressive to me. It's not that difficult to get a thin, flat ground blade to be hair popping sharp. But when you acheive that level of sharpness with a thick, convex blade you have really accomplished something noteworthy.
 
No, the convex grind does not give superior edge retention. Sometimes that "can" be the case, but it's not an accurate general statement. And it really isn't that hard to get a thick convex grind hair splitting sharp.

I hear you. That is why I was careful to say the convex grind "helps" with edge retention. I'm sure the main reason is the ZDP 189 steel heat treated to a rockwell of 67.
 
OK I hear you there. But the statement "helps give it superior edge retention", to me, comes off as if you are saying a convex grind has superior edge retention. One of my kitchen knives is ZDP189 with a 66HRC. It does have excellent edge retention, no doubt about it.

No it doesn't. The "thicker behind the edge stuff" is nonsense. For two matching edge angles, a convex has less behind the edge than a vee.

It's geometry. It's real.

Nope. It's fairly easy to refine a convex edge. Easier than a vee, in fact, since the process doesn't require a fixed angle throughout the process.

An edge is an edge. Doesn't matter what thickness the spine is.

Have you done much sharpening? I would highly suggest getting a knife, a couple grits of wet/dry, some cardboard, and convexing it.

It would bring more gravitas to your reviews.
 
Yeah....no.
They are certainly very nice and certainly very much overpriced. I have a Chi and I like it quite a bit despite this, since it is fairly unique and the blade is just so purddy. I have barely used it though, so I can't discount its potential to defy the very architecture of time and space ;)

Hey! Rockstead gets it!

" As for our Shinogizukuri blade, each side of the blade is composed of 2 planes. Shinogi is the Japanese word that describes the line created by the meeting of two surfaces. With this manufactureing process, we had developed a completely new and advanced technology. We realized that the optimal blade edge angle is 30 degrees near the haft, and the optimal blade edge angle is 24 degrees near the top of the blade. "

Draw a 24 degree angle. Fit a convex grind in it. The 24 degree vee grind is the angle you drew.
 
Yeah....no.
They are certainly very nice and certainly very much overpriced.

I'm not an edge retention nut, so I'm not willing to pay that kind of money for edge retention. I'm sure if someone is an edge retention nut, they are worth it, and not overpriced.

And that mirror edge is purddy, but you can get that mirror on AUS-8 with some Flitz/Mother's and elbow grease. In fact if you are maintaining your convex edges on a strop with black emery and chrome oxide compounds you are 3/4 of the way there. Those compounds are metal polish.
