Do you think he removes more than the 0.003" of steel that many skate techs recommend for figure skates, and therefore reduces blade lifetime? If so, that could be a major hidden cost associated with buying these blades.

By buying Revolution blades you are part of this happiness 

Quote from: Query on February 03, 2025, 01:16:33 PMDoes the blade holder he uses do anything to straighten warped blades while sharpening? He seems to assume he can just make straight passes and get proper edges.

No, it does not. If you didn't know, Gold Seals are tapered and side honed. It has to be a more modern skate holder which is able to straighten GS revolution blades

Quote from: Query on February 03, 2025, 01:16:33 PMDidn't you worry in an earlier thread that magnetically attached level gauges could magnetize the blade, and steel filings to stick to the blade during sharpening, and might mess up the sharpening?

Yes, its true that I do not like using magnetic BAT gauges since they leave residual magnet, but do you have better solution for these blades?

Quote from: Query on February 03, 2025, 01:16:33 PMDo you know anything about Wissota's Elite 3-D Universal Figure Skate Holder, which supposedly has a way to hold Revolution blades? (Does seem very expensive for businesses that don't sharpen a lot of Revolution blades, especially if they already have another blade holder.)

You need to use "hockey holder", like Wissota´s universal holder, which has narrow contact points for revolution blades. "Figure skate holders" does have too wide contact area and you cannot clamp revolution blades on them.

No, they do not. Even they would understand, they do not care since they do not need to sharpen them. How they look is more important for them. Gluing couple Chrystal strasses and they are even more attractive.

Qsior,
I can see that yuo are taking in account many things what many other people don't do. Highly appreciated!

I may be thinking about this all wrong.

The primary reason I bought the used skates are so I could experiment with cutting down the heel height. That could mean my foot interacts with the blade in a very different manner.

E.g., in my current heel height - which is about the same for my old boots and these used boots - I am normally at or beyond my comfortable limits of toe point. Which means I have to roll my whole body forwards to touch the toepick. But if I cut down the heel, I would normally be in a less pointed position, so I would be able to point my toe to reach the pick - like I guess most figure skaters do. I might even need a more aggressive toepick.

So until I have actually cut down the heel, worrying about blade shape is pointless.

I find it hard to spin and turn on the Jackson Freestyle boots+Ultima Aspire XP blades I bought.

The rocker radius transition point between the main rocker segment and the spin rocker segment is smoothed out, so I can't feel that point on the ice. Also the two blades are inconsistent in shape with each other.

The local shop has new boots+blades of the same type. The transitions are nice and abrupt. But the profiles of the left & right are different. If I line up the spin rockers, the backs depart from each other by roughly 1.5 mm.

Is that normal for Ultima now, or at least for Aspire XP? (When I placed my old Ultima Matrix 1 runners next to each other, I could not see any visible difference. But they were more expensive blades than Aspire XP, and bought in the early 2000s.)

It looks like the Canadian and Mexican tariffs were temporary.

The added 10% on China might turn out to be too.

There is a lot of complicated politics involved. I'm not going to try to keep track of this sort of thing, or worry about it for now.

Quote from: Kaitsu on February 02, 2025, 08:21:28 AMI would recommend to use same type in square than what I use. "The magic" in my square is knife edge. It does not create shadows like your, which ruler part is probably ~1mm thick. Thinner the contact area is, easier to see the light leak. You can demonstrate by putting you square rules flat part against the blade stanchion. See how much you see light leak. After this start to tilting you ruler until only the ruler edge contacts (45 degrees). My assumption is that first stanchion looks 100% straight but, when only the corner contacts you start to see some light leak. This is the reason why knife edge rulers are used in the quality controls.

on en apprends tout les jours... et un jour nous arriverons tous ensemble à la perfection!!

j'ai la même equerre que toi, et je vais essayer de limer doucement avec une 'triangle file'pour apointer l'equerre....

In a campaign promise, Trump said he would raise Chinese import tariffs to 60%.

Perhaps Jackson could move production elsewhere.

<<Emphasis added.>>  Trump wants the "elsewhere" to be the US.  But that won't necessarily translate to lower prices, though.

What I know, Ultima blades are manufactured in Taiwan.

Oh!

Quote from: Kaitsu on February 02, 2025, 08:25:15 AMGold Seal revolution is the much more trickier case. This blade designer only target must have been to make them visually pretty. Only flat area is in the behind the toe picks. Here is one method what JW recommends. https://www.youtube.com/watch?v=69tWd_K5iBI

Does the blade holder he uses do anything to straighten warped blades while sharpening? He seems to assume he can just make straight passes and get proper edges. Unless that is why he removes some of the Chrome plating?

QuoteI would recommend using similar BAT gauge than what Paramount introduces in their video. https://www.youtube.com/watch?v=JjVpbt8ePmc&t=334s

Didn't you worry in an earlier thread that magnetically attached level gauges could magnetize the blade, and steel filings to stick to the blade during sharpening, and might mess up the sharpening?

Interesting that Paramount sells gauges designed for other brands of blade.

QuoteNote that in Gold Seal revolutions it might not be smart to use skate holder which has wide contact area. Concave blade and flat counter face if not good combination. Hockey skate holder with narrow contact areas is much better for them.
