This is ATS-34 stainless with an 8” mirror finish hollow grind. Heat treat by Paul Bos to RC 59. The Amboyna Burl is as fine as you will find, has been stabilized by WSSI. The bolsters are 416ss and have a unique concave back of bolster design you don’t see often because it’s hard to do and takes a lot of time to get the tolerances close. A red liner adds some accent to the Amboyna.
