s-k, sometimes integral bolsters indicate an earlier knife, according to Bernie Levine. I haven't seen enough to know how often that is true, but I am sure the subject of bolsters could involve a long conversation! Apparently that J. Rodger's & Sons that I have is earlier, because of the integral bolsters.smiling-knife wrote:Hi upnorth. Yes it tapers along both dimensions. At the end shown in the first photo it is barely 1mm thick whereas at the blade end it is about 5mm thick. Perhaps the end the spring was made thin to facilitate the bend around the handle. The bolsters are attached rather than integral. With a magnifying glass there appears to be a seam visible. Thanks for your interest. Does this lead you to any conclusions?s-k
Being a newbie to that subject, I am just gathering information, which I thank you for!
