OK everyone,
Thanks to Scott I have received the definitive answer. Quite recently, i.e.: 2015 or 16, the shop has made the switch to 154 CM om "model #10's...only"! The reason for this change is due to the fact that the shop was receiving some stainless steel stock which had inclusions that required more effort than it should have to clean up.
The #10's, in all blade lengths are the only Randall model, at this time, being offered in 154 CM. The "other" statements made by the You-Tube guy, regardless of where or how he claims to have received his facts are incorrect. 2 examples below:
* #28's are forged
* Rosewood is the wooden scales used on the #10's..."not" walnut".
Hope this helps, Capt. Chris
PS: Thanks Scott & Jason
