Blade chatter

I've wanted to try the Fatip for this reason, well one of the reasons

Don't as their QC is garbage so they say. Specs all over the map is what most report.

I'm 3 for 3 with mine. They're brilliant.. If one is worried there's always BST . Or Amazon. It's $22 delivered for chrissakes from Connaught. Buy two.

Blade rigidity is an important factor for sure. As to what extent is subjective. I can tell the difference between a pre-war & post-war Gillette Tech in that the latter gives a slightly smoother shave as newer oval slots give better clamping close to the blade edge giving better rigidity. Of course, the greatest example is a SE razor which uses much thicker (read rigid) blades and scythes through multi day beard growths like a fat kid on a Snicbar.

Yep I thought fatip has surely got the QC up to par

Personally, I don't give it much thought. If a razor works, it works. If it doesn't, then it doesn't. Chatter has never factored into this as there can be so many other variables as well.

I think it's a complete non issue for most people, as the popularity of alternative designs aptly demonstrates. It's only an issue for me on a couple places on my head and only then going ATG.

jmudrick , I completely understand how it can affect your shaves and it is good that you are aware of it and can remedy it.

As rigid as it gets.

Which fatip is that? I used to own a fatip but that was years ago and I honestly don't remember what the shave was like.

That's a Grande Mk2. Same head as Piccolo, and different from Schone only by the number of teeth on the comb. Very refined shave, smooth, moderately aggressive (all exposure, no gap), much less than the narrow cap Mk1.

I am not sure I can feel chatter apart from harshness and weepers, but I am convinced it is there when I have too little blade rigidity (especially with significant blade exposure), I get blade resonance driven by the stubble. The people I know with fine hair are not sensitive to it.

The way I can tell I am getting chatter is to put a shim under the cutting blade. If this smooths out the razor (even though there is increased gap and exposure due to the shim), I know it was the stiffening of the shim that helped by raising the natural frequency of the blade in the razor and avoiding resonance.

I also think if slowing the speed of the stroke helps a lot, it might point to chatter in that it indicates your initial harshness was due to the range of impact frequencies of stubble on blade initially extending to the natural frequency of the blade in the razor (and slowing down separates the frequencies eliminating blade rsonance).

Interestingly enough, I don't think completely rigid razors are as smooth as ones that allow some flexibility while still having enough rigidity to avoid chatter. The Futur noted above is one that has less than perfect rigidity while being smooth.

What are some mild razors (say 2-3/10) that do a good job of clamping the blade? Preferably with significant blade curvature...

Fatip Gentile, RR Lupo, and RR Mambas come immediately to mind. Gentile bends the blade same as the Grande pictured above just with less exposure.
