Sadiejane - I responded to your PM but wanted to respond here as well. Dr. Lucie is aiming to have the book available at the BLADE Show this year. It will be tight time-wise and if not ready for BLADE it will be very soon after. So, it's imminent.
During the past five years I have examined and photographed (for the book) well over 100 Scagel knives, axes, self-made tools, pots,pans etc. It was one of those situations in life that occurs only once. Nobody but Jim has the credibility to pull all the big collectors together and convince them to get their Scagel knives out of the safe and bring them to me to photograph. Jim is in his 80s now and though very vigorous still, we won't get to have him around forever. So, this book is very significant in a number of ways.
As a result I have acquired a pretty good eye for accuracy in terms of Scagel reproductions and the nuances that are key. Unfortunately, most makers have seen and handled very few examples of Scagel's work and thus they are working with insufficient data - and it shows! This is nobody's fault. It's just that most of the best examples out there (the book will make this plain) live in safes and have not been seen in public ever, or in a very long time. Our hope is that the book will help these and other makers who have an interest in making Scagel style knives.
Thus, if it were me looking for a good Scagel repro/style blade right now, I'd start watching eBay for one of Jim Lucie's knives. He's the best by far at this for reasons I've explained. All the other makers mentioned above are worthy, no doubt, an no criticism is intended here. But hands down, Jim Lucie's knives are at the top of the pile.
Example (my photo of a knife Dr. Lucie made for me):
And, Sadiejane, I appreciate your interest and enthusiasm about this project and the knives of William Scagel so here's something special for you and the other readers of this thread. This image is one I prepared for the book that nobody has seen until now. It's my personal favorite of all the Scagel knives I've shot. I love the blade profile but more than that, the knife feels so 'right' in hand. That's one thing you just can't get from pictures. You'll notice that over the past 75-80 years some handle material shrinkage has exposed a small gap between blade and guard - everything pulled back toward the pin in the crown stag pommel.
