7 O'clock Razor Collection

I have the top left version in a rusty tin, it shaves really well, is it considered mild or aggressive compared to other razors, is the blade gap known, any info about it would be much appreciated.

I read that 7 oclock produced / invented the new slotted blade that we use today, is that correct.
 
The blade gap is almost non-existant with the open comb providing the blade contact. You need to use a very shallow angle with the handle near a right-angle to your face to get the best results from it. It's very efficient and can bite if you're not careful. I've only used it a couple of times but I recall one side seemed to be more aggressive than the other. Not sure if that's misalignment through age or whether it's by design. It's a truly great razor and one of Gillette's best designs.
I believe Gaisman was responsible for the slot design on the DE blade we use today. He was Chairman of Gillette at the time and also 7 o'clock as a subsidiary Company. The Gaisman rise to power is another story full of industrial intrigue that you could make a movie from. I would be surprised if the first slotted blade was anything other than Gillette branded.
 

Thank you for the interesting reply
 



 
Brand loyalty was very strong at the time, otherwise I think the name "Gillette" should have been retired and the company renamed "Gaisman".
He was in charge, the company used his patented blade design, and King Gillette was off writing books on Utopian Metropolis, they were no longer Gillette razors.
 

Gillette proposed replacing all North America’s cities with one giant city, built above, and powered by, Niagara Falls – an extreme version of the high-density designs advocated by many urban theorists and “re-wilding” conservationists today.

“Under a perfect economical system of production and distribution … there can be only one city on a continent, and possibly only one in the world,” he wrote. While citizens might temporarily occupy countryside or coastal dwellings for field labour or pleasure, the city, named Metropolis, would be their only permanent home, housing at least 60 million people at any one time.

Gillette described an urban area stretching from Niagara Falls around 60 miles eastwards into New York state, and a similar distance westwards from the falls into Ontario. His vision for renewable power might be considered ambitious even today.
 
Thats an amazing write up, the best explanation I have seen.
