Here is the lengthy, superb review of this razor by SharpSpine at The Original Safety Too forum, read "Day #7 of my Mongoose Journal", if you haven't already seen the review. I've read that the variety of blades available for the Mongoose, and various blades exposures and thickness, make this a very versatile SE razor:

Mongoose Stainless Steel SE | THE ORIGINAL SAFETY TOO

Here is an interesting section:

"So, what's the big deal with the Feather Super blades you ask? Well, I'm glad you asked. In comparison to the Feather Pro blades, the Supers are more than twice as thick (.31mm vs .15mm) & they are wider giving a larger blade exposure (1.42mm vs 1.2mm). As most people know, I love the traditional SE blades from GEM which are much thicker than the DE blades that most people use. What I didn't realize is that the GEM blade isn't even as thick as this Feather Super blade is (.23mm vs .31mm). I did think that the GEM blades were thicker but that misconception must come from the spine that is on the blade which I am sure does help to give even more rigidity. For further reference, the injector blades that I purchased from Ted Pella are listed as having a thickness of .25mm."


The entire 3 pages is worth the read, super review in my opinion.
