Yamato uses wooden stocks to suppress the targets chakra with his Wood Release.^[1] There are also two candle-like appendages on each end of the device similar to when Yamato used the Hokage-Style Sixty-Year-Old Technique — Kakuan Entering Society with Bliss-Bringing Hands technique during Naruto's training.

Trivia

• It should be noted that Yamato is never actually seen creating the stocks in the manga (even though the stocks are made of wood), so whether or not this was created by Yamato or was there from before is unknown. It is also possible that the stocks were made entirely of wood and illustrated as metal in the anime.
• As with the Hokage-Style Sixty-Year-Old Technique — Kakuan Entering Society with Bliss-Bringing Hands technique there were "candles" of sorts on each post in the manga. These are not present in the anime's depiction of the technique.
