No, the steel is molded with the holder

It is - you can make a patch with carbon or fiberglass and epoxy. But the stiffness won't be the same I think

Old Easton shins had that. Synergy 700 IIRC, those with transparent shin

Looking at the specs, steel "Fly compatible", so I assume it is not compatible to Edge.

Pretty sure no manufacturer uses different drills for copper rivers vs steel rivets. Coppers hold by their wide heads and washers, difference in fractions of millimeters is negligible

Use some plastic bucket. Cut the appropriate piece from it. Use hair dryer to set appropriate shape, and then use duct tape to fix the shape while cooling. Cut the stitches on the tendon guard, unglue the plastic piece from the liner and remove it. Insert your new piece, fix it with t-nut and flat screw. Glue and stitch the liner back

Hm, it's strange that they are not available anymore in US, in Russia they are in all major hockey retailers like Sportdepo (sportdepo.ru, in Russian only)

Yes, shins, elbows, shoulders, pants. Only one model of each in the series though

This is already a second version of their skates, the previous was called F1.1, i have those. The boot is very stiff and comfortable, can be compared to x800 at least in terms of stiffness and protection. The boot is fully heat moldable, the tongue on F1.1 reminds One95, a thick felt with stiff plastic insert. There are options with Tuuk holder and their own holder, the steel on both options is their own, but on their holder the runner is not replaceable. Overall fit for F1.1 is claimed to be similar to Vapor, but I would say it is a little wider. Also there is an option to order only boots, like True/vh offered earlier. The price for newest model with Tuuk is around 280$, with their holder around 180$, without holders at all around 160$. Previous model is slightly cheaper now. New model, that is shown on the upper video, have several improvements, and a new fit system like Bauer and CCM. Also they offer inline versions, and some features customisation if you order the skates directly. Overall these are great skates, I would compare them to maybe third Bauer model from top, currently 3x,, maybe these are even better (somewhere between 3x and 3x pro), but almost twice cheaper. Here in Russia they are gaining moderate success due to people's beliefs that Russian manufacturers can't make decent product, and Bauer is the one and only that can make good skates, and they don't have a good retail availability, which also slows their sales, but I hope they will continue to improve and take the market share they are worth of. They have Instagram account with photos and Vkontakte (Russian Facebook:)) page where there are some additional information and opinions of their customers, the company owner is also very open to dialogue via Vkontakte. And yes, they actually make it themselves, here in Yaroslavl.

Plus to stitching it. It is even possible to do it manually with a sewing awl and strong thread. I have even replaced the broken toe cap completely.

Guess this guy also doesn't know that he is a bender

Depends on what boot you will have. I have RBZ roller boot converted to ice snd there are no problems at all. I've even read somewhere that RBZ inline is stiffer that ice due to warmer temperatures it is used, abd therefore to provide adequate stiffness. The only thing that can cause discomfort is ventilation in toe cap, can be cold if you use it on outside rinks and sometimes snow gets into it.

Heard about similar problem on Tuuks, people just use dome stick tape on the runner

The toe cap is stitched to the boot sides and also fixed by 2 front rivets (may be 4, depends on the model). Don't see how it can be punched out, but I think that you can remove the rivets, cut the threads and move the toe cap a bit to the front if there will be some place to stitch it back and fix with the rivets. I've replaced the broken toe cap on my skates, so I think this is possible. But not the easiest way, if I had the same problem, I would go with toe inserts.

I guess eBay or Sidelineswap is your choice
