Thanks all. A few of the suggested sources seem to lack a web presence that shows actual blade blanks, and others don't seem to do what I'm looking for. I'm also looking for something made from bar stock rather than forged, and I'm afraid I'm not on Instagram (need an account to view Jimmy Pie's stuff). To clarify, I want to make something very close to my current knife...
Aside from a general interest in making the knife, the change I want to make is to the shape of the handle - I want to try something that's a bit fatter. I sometimes find this a bit slim for forehand power cuts, while a shorter blade that I handled some time ago, with a bigger palm swell, feels better. Incidentally, the full tang on this is non-tapered.
Also, I just measured the bevel on the current knife, and it's closer to 7.5mm high (measured parallel to the main surface of the blade), which equates to 30° included angle. Another thing I like is the fairly short ricasso (about 6mm), and the fact that the grind ends vertically (easier to hone at the edge of a stone). This feature is quite different from the original Woodlore...

When I went looking a little while ago, I found Bernie Garland's web site and saw that he does blanks that are pretty close...

...and it was these that got me thinking.
