Looking for a twiddling JKpen blade

[Shimamura]

Are there somem JK pen blades that can be twiddled ?
I currently mostly use short pips & a tradtional penholder (not reverse or hybrid penhold).
I have good serves and want to use inverted for serves and twiddle back to short pips.
Of course eventually I want to llearn to loop using inverted from forehand as well as RPB backhand loop.

I heard there are some JK penhodl blades that can be twiddled.
Please post if you know of any.

I think there are some Butterfly but I think they are very expensive
Any cheaper Chinese options ?
