【8FLIGHT】REGULAR FIXED SHAFT BLACK 19mm 's Japan Review

I bought it because the flight joint is threaded.
First of all, the shaft is not carbon, but it is rigid and does not wriggle while flying.
The flight side is also firmly screwed in place and does not loosen or come off, making it stress-free.
Also, the special joint is a good thing because even if the shaft breaks off inside the flight, you can remove the remaining shaft by turning it with a sharp-edged remover.
I am not sure about the durability of this product as I have just started using it, but I think it is the best product I have ever used in terms of eliminating the stress of loose shafts and flight detachment.

I bought a 330mm shaft to change from L-style to 8-flight.
The number of screws on the barrel side is less than half of a normal shaft, and the jagged edges of the screws cannot withstand the impact, so they are shaved off and fall out immediately.
I think this is a part that needs to be fixed.

Barrel side thread breakage is serious.
It's incompetence to release something that's so good but has no durability.
It's meaningless to eliminate the flight disconnection.

It's a pity that it's no different from the products of a certain manufacturer's followers.
