【世界に2本】Z-EALを金ピカにしたら、メーカーが来た

[Only 2 in the World] Driven purely by personal curiosity and a mischievous whim, we've given Ko-ken (Yamashita Kogyo Kenkyusho) their renowned ratchet, the "Z-EAL," a gold-plated (TiN coated) version. ▶A long interview with Ko-ken's development manager, Mr. Morita, is also available.    • Ko-ken Z-EAL｜なぜ36ギアなのか？開発者が語る“本当の理由”と空転トルクの秘密   This isn't just ordinary gold plating. It's genuine vacuum plating, "PVD (ion plating)," the same process used for drills and other tools. However, wouldn't the extremely high temperature of "450 degrees" during application disrupt the precision (tolerance) of the ratchet…? So, we had Mr. Morita from Ko-ken "fly over" to Saitama to conduct a thorough verification using drawings and 3D measuring machine data! Please enjoy this ultimate silly project, officially sanctioned by the manufacturer (?), until the very end! If you have any fantasies about making a crazy tool like this, or any thoughts on the video, please write them in the comments section. I read them all! And if you think, "They're being silly lol," please give it a thumbs up (like button)! It encourages me! 👇【Table of Contents (Chapters)】You can jump to your favorite scene from here! 0:00 It finally arrived! Unveiling the golden Z-EAL ratchet (3725Z) 1:33 Why did I choose Z-EAL?

In 1999, we founded the current "ABIT Tool Specialty Store," and continue to operate with just one store in Saitama Prefecture, directly interacting with customers in person. The reason we started this channel is because we wanted to deliver honest tool information that isn't found in catalogs. We talk about things that are difficult to convey online, things you only understand after using the product, from the perspective of a specialty store. A little excuse All videos are basically unscripted and filmed in one take.
