I bought these the other day. This seems like the way to go to me for foil torx bolts.

I use a T-handle wrench. The weight of the T-handle acts as a flywheel and spins the screw very fast. It's quicker than an electric screwdriver without the risk of crossthreading.

Finger pressure on the T-handle is enough to get the screws tight without the risk of overtightening.

It's not stainless steel. The web site says a "black phosphate" finish. There is a little discolouration of the end, but no actual corrosion.

I have used mine for about 400 sessions. I do a full assembly every session. During disassembly I blow excess water out of the screw heads and give the area a wipe with a chamois cloth.

I used Wera stainless steel hex keys in a ratchet driver before I got the T-handle.

Anything I get that is steal will rust and have a limited life span. My good steal t handle set and ratchets stay at home.

The t handles and d handles in t40 are too big to spin on the mast attachment to the board. Even the t30 will knock the mast.

These l keys do not.

The ratchets in stainless are expensive, the non stainless won’t last.

Stainless screwdriver does not give you enough purchase to really tighten.

I can put stainless tools in my bag and take it to the beach if I need to fine adjust things and not worry about rust.

Steel tools will leave behind some residue and you will see more rust on your stainless screws as a result.

The stainless l keys have some heft but do not spin like t handles but they are easy to spin by hand quickly. They are also lighter which can be an advantage when traveling. On my last trip I was a .1 lbs from overweight on both my bags,

I admire that you take everything apart, blow out all the water and wipe it all down with a chamois.

I don’t but occasionally I do take it all apart, just not at the beach.

But with my current vehicle I do have to take the mast off and on each time so I need something quick to turn a few whole turns but long enough to do a final torque.

Got me a Torx screwdriver today. Might stop me over tightening things for once...!

Agree over tighting is a big issue as one does not want to loose that valuable foil.
But when wore out after a session one has a problem.
My suggestion tighten with a normal screw driver type totx head and undo with a leaver type.

I do a lot of maintenance on delicate carbon parts on bikes with a torque wrench. My opinion for me, it is impossible to get things tight with a screwdriver.

T handles, d handles, l wrenches or ratchets are needed.

Foils are not anywhere as delicate as carbon seat posts, seat rails, bars, or front fork.

But maybe I am just a wimp.

I can put a bar through the handle of the screwdriver if needs be...

In my experience the only things that are hard to tighten are worn hex heads. It's really hard to get the leverage to get the screw tight so you end up overtightening them and further damaging the head and/or the driver.

With a Torx head you get a very positive lock on the screw head. It is easy to tighten the screw without overcranking it. There's no wear on the screw head or the driver.

Small Phillips head screws are very bad. So far the very big Phillips screws on my GoFoil have a very positive lock with the screwdriver.

Tuttle head masts and GoFoil style foils need very little tightening for a solid connection. For kite foiling there is no way I would buy a foil with wings held on by screws. Either a one piece glider, or integrated wing and fuse ends only.

Love the Wera stainless steel tools for my foils. The tools that come with foils are ridiculous for a mostly salt water activity.

Screwdriver /handle/ all the way. Also on bikes. You dont need leverage for such small sizes.

Sometimes i have feeling that we are solving nonexistent problems

Edit
I mean Torx tool with screwdriver handle - not Phillips head and screws which should be prohibited in 2020!!!
