Wealth of information and imagery there Jack, much food for thought and daydreaming. Very grateful you could upload it.
Couple of observations: let me get in my time machine and out into that showroom as shown on p.16 please! The Stag store picture I've seen on this Forum already, and it provokes a lot of daydreams. The Tusk room I hadn't seen but I have to admit to more mixed feelings about that...
Something really struck me on p.27 . They use the word 'scales' for the handles of a knife, I used to use this word until I got 'corrected' by somebody in the business and allegedly in the know that 'scales' are brass or metal liners. But now I can read from a 1911 original horse's mouth that this was the word they used then. Good enough for me, back to scales it is! I've never fancied the term 'covers' as this to me implies something that can be quickly changed or hides something...

Also on p.27 they lay weight on the need to let materials for scales mature or age. This extends even to celluloid types (2 years wait) and I found this significant. Even very old Cell knives can be found in a stable condition and this may be why. This maturing/waiting aspect can especially apt for horn knives. I've seen some horn knives from the 1850s in very OK shape and yet some of their modern counterparts can be in a pitiful state of warp/shrink after only months or a couple of years. I've long suspected that curing techniques may have been lost but now it could be a simple maturation thing, well, after all you can't drink decent whiskey or brandy unless you let it be for a few years!

Could make sense with natural materials as well.
They stress their defining notion as the maintenance of quality over mere price, this too is significant, they also note that the Rodgers name gets pirated by inferior marques but the discerning consumer won't be palmed off by this without the unique trade marks on the tang! How tragic they (or Sheffield as a whole) were unable or unwilling to maintain quality first in the decades that followed this catalogue. This quality is, they plainly admit, also due to the diligence, skill and loyalty of their workmen. It is rather sad when you look at that photo of all those old boys with so much accumulated knowledge and expertise on the brink of eternity. To think what happened to their successors and apprentices, many must have perished or been maimed in the Great War, just a stone's throw away from that photo. The loss of life, way of life, hereditary skills etc.
Lots to ponder about in this wonderful catalogue. I believe that so long as people are interested in owning, using and talking about Traditional style knives from around the world, the skills of these long dead men are renewed in homage every day. Just let me fix up that time-travel machine...
Regards to all, Will
