A post on FB with a PAA Starling SE prototype...... Interesting.

Thanks for posting this thread, EFDan!

I would definitely pick up the PAA GEM razor when it's available. Especially if it is priced at $25.

It's crazy how 0.01mm can make that much of a difference isn't it?

Ba-dum psssh!

Lol people actually think Gem blades are still being produced to supply shavers???  Deear Murica, you used to be to voice of common sense... used to be....

Actually, they are.

Industrial blades are manufactured at a blade thickness of 0.1mm at the edge. Shaving blades are manufactured at 0.09mm at the edge.

Industrial blades are not coated. Shaving blades have a PTFE teflon coating.

GEM Blue Star carbon steel blades are manufactured as a shaving blade and are not intended to be used as a scraper.

Shaving may not be a primary user group for the production of single edge blades but they are still a recognized user group, and there are still blades currently in production designed to be used as a shaving blade, as opposed to a scraper.

Have you ever tried to scrape paint with a blade designed for shaving? They break. Quickly. I wouldn't even attempt to remove silicone from a roof flashing with one...

And those white plastic inserts for the brown coffee cups are still available through Uline, last time I checked. Look under "hospitality". Just FYI...

so what you saying is the 0.1mm makes that much difference that if one tries to scrape with it some paint from a window it will break? Don't forget the PTFE ones are not marketed as shaving blades and yet they are the best of all Gems for shaving

While that .01 mm may not make a world of difference in shaving, it is a way to differentiate between the two when making a purchase. As a consumer you know your razor needs 0.09, and your scraper need 0.10. This also helps the manufacturer to keep the two lines different, or just prevent them being mixed up.

That 0.1mm does make a big difference. In shaving edges, the difference between smooth and comfy, and rough and tuggy, is measured in microns.

You want the apex of the edge as thin as possible without manufacturing fragility or brittleness into the edge.

As for medical and laboratory applications...yea, Personna has been making medical blades for a long time.

Lab blues are very popular with shavers despite the fact that Personna does not market them for shaving...

Sure, you could scrape paint from a window. You could scrape creosote from a fireplace pyroceramic door glass. You could scrape candle wax from a hardwood floor. Soft materials scraped from smooth surfaces should present no problem for even a thin plastic scraper.

You could not scrape buffing wax from a linoleum floor. You could not scrape exterior paint from wood siding. You could not scrape silicone caulking from around a roof flashing. Tough materials scraped from an unevenly textured surface would cause almost immediate breakage.

The other aspect of the equation is the fact that the more refined edge at 0.09mm will dull and become damaged much more quickly than the more coarse .10mm edge. This is a matter of edge science. The finer the edge, the easier it is to damage. That's why shaving will dull a brand new blade quickly...

Personna doesn't market Lab Blues as a shaving blade either. Yet they are a highly desireable shaving blade well liked by most DE users. Funny, ain't it?

Well, you can always go vintage. I them come up from time to time.

I'm not sure if these ones are SS or Carbon:

I don't have any GEM blades. I suppose I've been curious but I didn't have enough push to get one.. would love to see the reviews.

I've used GEM and EverReady SE razors for years with GEM Stainless Steel coated blades.  They are fabulous razors and with the GEM blade give great shaves.  I love my 100 plus year old lather catcher, my 1912, 1924 and Streamline.  I have had trouble with my Micromatics but boy are those high quality razors.

I'm very much looking forward to seeing this new crop of SE razors.  This one is a fine looking razor and I have no doubt that the Blackland will be stunning.


If you haven't shaved with an SE, try one, especially the 1912, and you'll have a very hard time not getting hooked.
