Excellent first shave and then dulls fast resulting in a nick or not a close shave.
Derby Premium

This blade makes a very good first shave.
Second shaves yield either irritation, nicks or not close enough. An average shave.

2/6 shaves were not close

Astra Superior Platinum
2 blades 8 shaves
Average score: 0.996875
This combo produces excellent shaves with few issues. No irritation, 1 nick in 8 shaves, very close and very smooth. The 1 nick was probably technique related. The shaves are near BBS.

A very good blade that retains smoothness and sufficient sharpness through 3 shaves in the EJ 3ONE6.

Gillette Perma-Sharp Gold box
Rex Supply Co Envoy
3 blades 15 shaves
Average score: 1.0
No nicks or cuts, no irritation, mostly BBS in shave quality and closeness, very smooth result. All a pleasant shave experience.
The blades last 5 shaves easily.
Edwin Jagger 3ONE6
Gillette Perma-Sharp (Gold Box)
2 blades used on 10 shaves
On the first blade, 3rd shave, a nick on the chin was created which kept reopening on subsequent shaves. I shaved with less efficient tools for 2 days allowing this site to heal. First two shaves on this blade were excellent showing the potential of this combo.
On the second blade I started with a facial cleanser and showered after shaving. Additionally, I used a much lighter touch and used caution on the chin area. With those two changes, the combo achieved 5 really nice shaves.
At this time I prefer the Rex Envoy + Gillette Perma-Sharp combo over the Edwin Jagger 3ONE6 + Gillette Perma-Sharp. The Envoy appears more efficient with less risk of creating a nick. However, it is very easy to over shave with it. The 3ONE6 appears less efficient and easier to generate cuts or nicks. However, I’m not likely to over shave with it. There maybe another blade that makes the 3ONE6 truly shine.
Rex Supply Co Envoy
Bic Chrome Platinum
2 blades 8 shaves
8 irritation free shaves ranging from DFS to BBS
These blades are not as sharp as the Gillette Perma-Sharp (Russia) but they are nice and smooth through 4 shaves.
YMMV
