Thank you for viewing! I plan to list many custom tools in the future. This product has a titanium coating. The bent areas and areas that have been heated have lost their color. It has been polished with a blue buff. After purchase, I will make and ship one with the same specifications! There may be slight differences. A 4-twist version will be made for 7000 yen!
