New USA Personna blade?

I've read a few reports over at B&B and they are all very complimentary towards the new Personna, seems like it is a winner.

Sorry, no Personna blade could ever be a winner as it doesn't have Mr Tendulkar on the sleeve.

It looks like it, Personna GEM DE blade.

Found here.
Looks very similar to the very expensive AccuTech Med Prep box.

As for the Comfort Coating Lab Blue the newer no logo Personna 100 pack of made in USA are so coated they take 7 shaves before the coating wares off now and then the usual after coating is gone on average 3 shaves before they dull down. The blades seem to look like the old Comfort Coated Lab Blue people had in reviews of where the reviewers say it took a week of use to get rid of the coating. I say this because I use the Personna 100 Pack made in USA and older blades that feel like more a standard coated blade with an actual logo on the blade, not this overly slick blade like the newer Personna 100 pack made in USA without a logo I got in early 2025.

On another forum a fella did an analysis of the new GEM steel and lo & behold it's not the same as their other DE blades. It's the Japanese type used in Feather blades. That's interesting, but only as regards the Rockwell hardness. Despite Youtube knife nerds slobbering over the newest small batch 'super steels', e.g., Magnacut, the experts tell us blade heat treatment and edge geometry are far more important factors than steel type. That is why Feather blades seem so sharp......for the first shave. They have a triple edge grind and the fine edge simply abrades away quickly just as with any blade with the wrong edge angle for endurance. A knife with a 30° edge grind will holds its edge longer than one with 20° under normal usage as a rule.

This explains my cheap 10 blades from FEIYU a Chinese brand that came with a case that had a cheap plastic butterfly shaver I got on sales on AliExpress for $1.05 USA where I tossed the shaver for the case to hold normally my Micro Touch One only using on vacation for my Gillette adjustable 1960's era whichever is the top model at the time. The FEIU I in the single test of one blade I only got 5--6 good shaves when on 7 having to ditch the blade with this limit was both sides were dull after this even trying to flip after day 6, part of this was due to how soft the Stainless Steel was and the other was the mild shave angle probably under 20 degrees but defiantly above 15 degrees as blades like this tend to not cut at all. My others at 20--25 degrees like the older 2017 Personna made in USA 100 pack is higher degrees bevel in the 20--25 degree range with a thicker blade getting 35---45 shaver while my bought in early 2025 Personna made in USA 100 pack blades are a slightly lower bevel in the 20--25 degree range with ever so slightly thinner blade that gets 30--35 shaves usually though I have pushed one blade due to being on vacation and not wanting to start a new blade up to 40 shaves where at 37--38 was the limit. The 10 cheap

The thickness of blades is why I can't use the Dorco ST 300 and same blade in STP 301 meaning comfort coated with old logo (have not tried the new logo) as they rip out my hair due in part to how short the bevel is despite being a normal sharpness shaver slightly behind my older 2017 Personna made in USA 100 pack. The Dorco are too thick almost that of the old Treat Carbon Steel Black Beauty blades where with the Treat Carbon Steel Black Beauty blades they need to be this thick for the lesser steel to maintain an edge but are really just made for users of Pre WWII shavers where stainless steel was not common for shaving blades due to how expensive the shaver is.

I have felt some Treat carbon steel Black Beauty blades in an antiques shop in 2017 that is now long gone since 2019 where the Treat Carbon steel Black Beauty blades were with an old shaver a screw top model of useless in my eyes pocket travel Gillette razor with case opened up for display where one blade was missing the wrapper of the 5+1 pack with the end open, missing the tab/flaps. I threw away the probably partially used blade that was missing its wrapper for safety into the trash near the counter. The travel set was missing the middle section of the shaver handle so either it was the super micro version of travel shaver or this was missing a section. I know it now as the Travel set but at the time in 2017 I thought this was a Gillette WWI issue sets using the design for portability given the colors of olive drab used but I think King Gillette was most likely trying to use up the fabric color he had left from WWI in the 1920's before moving on to the tan/natural off white.
