Bladed spoke - seized nipple. Advice?

Hey folks

So my mate works for a charity shop over here, and he saw a bike wheel poking out of their skip. Knowing I'm a nerd for such things, he picked it up and gave it to me. Turns out it's a bit fancy: mavic aksium race rim with bladed spokes and 10 speed aksium race hub. It looks nice and true, but the spoke tension has dropped noticeably on the NDS on a few spokes. So I got my wrench on them today, but the spokes are just spinning in the hub when I turn the nipples.

This is my first aero wheel (being more of a C&V guy usually) so forgive me if I have no clue here. I've sprayed some WD40 on the offending nipples and I want to gently loosen them if I can. Is it ok to use some flat pliers or something to keep the blade still while I turn the nipple. How fragile are they? Do I just need to replace the seized ones?

The rim looks like it has plenty of life left in it, so I'd like to resurrect the wheel if possible. Your wisdom is greatly appreciated. Thanks in advance

Maybe the proprietary nature of those (ie you need to get Mavic Parts From Mavic) is why it went in the bin.

My go-to item for any seized joints is Kano Kroil; PB Blaster is second and regular WD-40 isn't in the running. You can use anything to hold the spoke which does not mar it. It would be simple to make a piece of metal with a slot as a spoke holder (I like making tools).

Thanks for your input folks, I did wonder about making a tool to keep the spoke blade in place. Think I'll have a crack at that. I wondered about penetrating oil (which I'll try if they don't loosen up) but thought WD40 would be a good fit because it attacks the corrosion?

So slightly off topic, does anyone actually use bladed spokes on their own bikes?

Bikes: Too many. Cannondale SuperSix, Trek Remedy 8, Trek Crossrip+ get the most ride time.

The only real downside to bladed spokes is the price. I like that they make spoke windup obvious during building, and the extra shaping makes them slightly stronger, and they're a touch more aero, and sometimes they sound cool. I consider them to be a small bonus on a stock or prebuilt wheel. But I'm just not down to pay for them on the wheels I build generally.

It depends on how badly and how many are seized. The above recommended penetrants are good and I have also used acetone/ATF homebrew. I put a drop on each nipple, spin the wheel to drive it down into the threads, best to use a four sided spoke wrench, then loosen the nipple, really bad ones (lower grade aluminum/) will round anyway. We have a Ritchey WCS wheelset waiting for total replacement of nipples, despite numerous atempts to loosen with repeated penetrant they round and take pliers to remove. I will replace all of them with brass nipples

God I'm such an idiot sometimes. A drop on each nipple and then spin the wheel! Why have I been hanging the wheel and putting oil in the other side and rotating it every few hours?

Bear with me folks, this could take a while

Thanks again for your help & replies

**Update** (in case anyone's interested and generally for posterity)

Having doused all the nipples in penetrating oil, I followed the advice of my LBS mechanic, who told me that in the absence of the correct size tool, he just uses a good pair of pliers with flat ends, wrapped in a cloth to protect the spoke. With a bit of effort, I got them all moving, no damage to the spokes whatsoever.

Now I have a fully working wheel I have absolutely no use for. Yay!
