Just for people who didn't watch the video. They could only fit 12 bits in that they determined to be "optimal size" handle by making them half-size. But they disliked the idea of locking people into their bits, and changed the design so that a little rotation can adapt the storage area to 6 standard-sized bits.

Here is a link to the relevant section https://www.youtube.com/watch?v=2K5Gqp1cEcM&t=819s

They do support full size bits. Though you will be only able to store 6 full size bits instead of 12 small bits. https://cdn.shopify.com/s/files/1/0522/2980/0129/files/Addit...

Did you all not watch the video before complaining? He specifically mentioned this, its designed so yoi can also have normal bits in the bitset
