Plenty of posts describing the difference between the knot shapes, including pictures for a visual comparison. In addition to that, fan knots do not have the glue bump. In my experience, anyway.
In my experience the knot shape has no bearing on whether you can feel a glue bump. All knots have a glue bump or maybe better described as the top of the glue mass holding the fibers together. The higher the glue mass the more likely it will extend beyond the top of the handle.Plenty of posts describing the difference between the knot shapes, including pictures for a visual comparison.

I can discern between any brush I have with a fan knot and a bulb one blindfolded. Either during its use or just simply by feeling the knot near the top of the handle. Of course, that is for all the brushes I have. I can feel the glue bump for all the bulb knots (and some of the hybrid) because the glue bump projects over the top of the handle.In my experience the knot shape has no bearing on whether you can feel a glue bump...
You sound very knowledgeable. I admit, I do not know how all knots are made. My statement was not correct indeed, and will rephrase it. In my experience, the fan brushes I use do not have a glue bump extended past the top of the handle. Very likely due to a shorter glue plug. And that makes for me a better brush....All knots have a glue bump or maybe better described as the top of the glue mass holding the fibers together...
I believe it depends on the brush manufacturer how deep they set the knot in the handle....The higher the glue mass the more likely it will extend beyond the top of the handle.

That being said, I prefer fan brushes over bulb. I consider all fan brushes I have being better brushes, when it comes to performance.
The only way I can really tell if the glue bump extends above the top of the handle is by pushing a straightened paper clip down through the middle of the top of the knot until it stops. I mark the clip at the top and then measure it.I can discern between any brush I have with a fan knot and a bulb one blindfolded.

Have you ever considered that first brush as atypical for a fan brush? Maybe even a defect in the knot?I have a custom made brush...
Just how I like them....perfect with a 0mm glue bump...
I've noticed my old Semogue boars have huge glue bumps. They perform great. But I have to resist looking for the bump. Just knowing it's there bothers me.Just how I like them.
Yes it would be atypical/defective for any type of knot be it fan, bulb or hybrid that has a 10mm glue bump. I have another brush from the same manufacturer that has a negative 4mm glue bump. I always thought it was a little floppy, but never measured it until I ran into the 10mm glue bump. My 4 other brushes from this manufacture are all 1-2mm positive bumps. My 11 Simpson brushes are all from 0-3mm positive.Have you ever considered that first brush as atypical for a fan brush? Maybe even a defect in the knot?
I dislike brushes with glue bump extended past the handle.
The only way I can measure the size of the glue bump that extends past the handle is by doing this: "pushing a straightened paper clip down through the middle of the top of the knot until it stops. I mark the clip at the top and then measure it."
If I want a quick assessment, I just pinch the knot right above the handle.
