my guess is that these are still using OTF design, but flipped upside down, so that the blade can be shown on top, and the ring's string is below, hence why the string is closer to the wrist and in the bottom layer.
@@ivanvanko1763 You can follow me on my Facebook account. In fact, I have developed a gear transmission structure that can overcome gravity, and I will make a stainless steel version of it in the near future, but the buyer will have to pay a higher price.
I will consider purchasing a hidden blade from you in the future. What material is it made of? Aluminum or steel? If it is steel, could you tell me what steel it is?
I think it’s 304 and 305 stainless steel. I have the one from this video: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-x9MPDRTx990.htmlsi=-ULI6PmjepA7AeqH
@@l.h.y4370 Thank you very much for your reply, I saw a hidden blade with gears on your Facebook, I'll save up some money and then decide which one to buy.
