Bear in mind that the knife wasn't designed for tip work but for cutting thin material like split leather I believe. But to use it as intended would have the bevel against the ferrule as we make these cuts. These knives are made for very accurate light work. I think when taking an existing tip off of a ferrule it is more of a break than cut, not something these knives are intended for. Use a rough tool for that, even a sharp wood chisel. I usually cut the tip off just far enough out I can see I am cutting or breaking the tip, not the tip/ferrule joint or cutting into the ferrule. Then, if you want to take a precise cut of that last ten to thirty thousandths of leather off the end of the cue, slice it off with this knife.
The proper usage is indeed with the bevel of the blade against the ferrule for all cuts. I suspect it would take a little practice to get used to the idea. Generally tooling call out is backwards, left hand tooling for a right handed person and vice-versa. When you get in the habit of looking at the bevel instead of the back of the blade you now see very close to the junction of the material being cut and the cutting tool, not the back of a blade that might be over an inch away. Makes sense, in theory. I suspect something that needs some rethinking and practice on our part.
One of those things I never get around to is leather work. I suspect leatherworkers would be more familiar with this knife and how to use it, particularly Japanese leather workers if I recall correctly where it originated. It may well be a second cutting tool too, to be used for a final trim after the bulk of the waste has been cut away as I suggested in tip work.
I have considered buying a few of these knives a handful of times. Never got around to buying them but while I was looking I learned the intended usage of one. It isn't intuitive, but then again many things aren't.
