Kodiak Shaving is run by a really nice guy. The “Personna” branding is a bit of a mess. Even since I’ve started wetshaving (7 years ago) there has been a flurry of changes with the branding.

The blades you liked were most likely colloquially known as “Personna Lab Blue” which say “Comfort Coated” on them. You can still get them here https://kodiakshaving.com/products/personna-double-edge-blades?variant=52331003969903.

I personally like both blades. Some people think they’re the same (they do come from the same factory in the USA) just in different packaging, but I’ve found the GEM branded ones slightly smoother. Every face is different, though.

I don’t know what your price limit is, but I think $16-$18 is a good deal for 100 blades ($20 with shipping, of course).
